This thread could be used like a database for games ported from various plataforms. Sorry for authors but if somebody is interested will be routed for the links and will know the devs responsible.

Released:
2048 - SMS
Arcade Volleyball - SMS
Battle city - SMS
Bruce Lee - SMS
Cimmerian - SMS
Donkey - SMS
Do the Same - SMS
Grail of the Gods - SMS
Green Beret - SMS
Qbasic Gorillas - SMS
Picross - SMS
Skazka - SMS
Tetris - GG/SMS
Where Is It? - SMS
Wing Warriors - SMS/GG



In progress:
TMNT 2 -SMS
Alter Ego - SMS
Castlevania - SMS
PS II - SMS
Megaman 2 - SMS
Prince of Persia - SG-1000
Final Fantasy - SMS
N game - SMS

Desired:
This space is for members ask to devs how much is a game doable to be ported for sega 8bit systems. Not will be counted madness. For example, supermaxx thinking that Last of Us could be ported. For example, a DOS game, Warcraft could be ported? Even being a DOS game consume much resources.

Realistically, it would be possible, but would have to be heavily trimmed down.

For some RTS games made for 8 bit platforms, you could take a look at Planet X2, for C64:


Or Warlocked for GBC:
%3D%3D

Maybe a Warcraft-themed tower defense would be more feasible?

One game I would like to make is Cybernoid. It wouldn't be far from what I've learned and made so far so it's definitely doable.

I would make it based on the ZX Spectrum version (my favourite) but obviously with more colour depth and detail.

Here's the Amiga, Amstrad, C64, and ZX Spectrum versons.

Haroldo this GBC game seems very close to me.Although 32 KB of RAM is much more than our SMS.

Yes, it would have to be seriously cut down to work on the hardware.

I don’t know, but maybe it would be a good idea to distinguish between port and conversion, as in actually using the same code base vs remaking from scratch.

For example, Do The Same is a port of the Colecovision version while Green Beret is clearly a conversion of the game, probably the NES version.

Some to add to the list:
Where Is It? (port)
Skazka (port)
Bruce Lee (conversion)

Definitely doable. If based on the Spectrum version, you can even use the screen/room layouts 1:1, because it has the same resolution as the Master System.

I seem to remember, though, that there was some kind of weapon switching with keyboard keys, so you'd have to come up with a good solution for that. I'd also define some kind of cutoff point that stops new enemies from spawning when you are near the edge of the screen where they appear, as I remember that driving me mad when I played it back in the day.

Exolon, also by Raffaele Cecco would be another great candidate for an SMS conversion.

I dont was aware. I was thinking that difference between port and remake would be 1 Port - game that follow the same characteristics from original (Graphics, music, game map). Example: Megaman 2 from gvx32 while 2 - Remake - game with musics, level designs, sprites Example: Castle of Illusion for Switch. But i prefered put other expression (i accept suggestions) than separe in 3 or 4 categories. "Converted" would be better?

Green Beret is following the Arcade version i guess.

I think "converted" would be a good term, because it encompasses both real ports and enhanced remakes too, but not the other way around.

Dear god, no! The game is merely inspired by Mermaid Madness and has a similar story, but it has very different game mechanics, level maps, characters, etc.

One old game that could work well on the SMS would be Flightmare:


Highway Hunter looks like it could also work well on the SMS:

Taking a look at "nano JAMMER":
https://morgan3d.github.io/nano/doc/specification.md.html?utm_source=pocket_save...

It looks very simple, and it looks like it would be possible to create a converter to automatically convert its games to SMS, within certain limitations.

Grail of the Gods is a (pretty good) conversion:

https://www.smspower.org/forums/19569-GrailOfTheGods

Also, there's this version of Tetris:

https://under4mhz.itch.io/bloktris

...And... Isn't under4mhz's Wolfenstein another (impressive) conversion?

https://www.smspower.org/forums/19054-Maze3d

Also, let's not forget the amazing conversion of Picross by Maxim:

Seems for me that of this list:
1 - Grail of Gods seems that got the feel from original and will be added.
2 - I was in doubt about Bloktris because it use a background So i was thinking that would be a tetramino with graphics but i saw that follow orignals elements like music. it will be added.
3 - Im in doubt if Maze3d follow up the same levels, levelmap, musics from Wolfstein 3D or use an engine with some similarities.
4 - Sincerely i dont know if picross is a port.
Thanks a lot.

It is a different engine, and it only reproduces the shareware chapter, but the level layouts and the music try to mimic the original as best as the Master System can. I understand your choice of not including it, but I think one of the nicest things about 8-bit machines is seeing how programmers must (and do) demake games which would otherwise be unthinkable.

I found this DOS game:

It seems simple but i got thinking if would be doable in SMS. Moreover could Little Nemo (NES) to be ported/converted for our SMS?
My question will to "House of Toys" stage that seems complex:

BTW, i loved Little Nemo in back days.

I know this is extremely niche, but I hope someone will make a Master System port of Gotta Protectors: Amazon's Running Diet. It's a neat little NES game with music made by Yuzo Koshiro, and I think it would look even better in SMS's graphics

I'm working on a port of a NES game. While I won't say what it is just yet, I aim to reveal all by the end of the year. It's in a fairly advanced state, but I want to clean up a few things before showing it off. There is a user on these forums who is aware of it and has received a few builds of it, the most recent one being about a week ago. I won't reveal who that is either as I have not discussed that with them, but if you're reading this, you're welcome to vouch for me, or not.

If I don't show off anything by around the middle of December, feel free to be skeptical, and if I don't get where I want to by New Years Eve, I'll spill the beans anyway.

Do you can reveal to us which platform (console or not) you will port?

NES is correct! Sorry I'm being cryptic for a minute, but all will be revealed in weeks. I just want the reveal to look and sound a bit better than it does this very minute.

OK. At least you could reveal if the port is from of any big software house (Ni****do, Capcom, Konami) or is from other software house? LOL.

I dont see problems in ask (for curiosity) hints about port. Let´s say that i stated be porting a sunsoft game. Not is necessary that anybody will know which game is being ported in specific. I can try guess tha is Gimmick but can be Batman, BROJ, Blaster Master, Journey to Sillius, Gremilins 2... In case, he also dont need answer and will can do it anytime when he want.

Ok. To clarify my previous comments, I'm porting a game made by Ni****do. I won't say which one, but at the moment, 2 users (including the originator of this thread) should be able to verify that I'm not making this up. I know that Ni****do like to do the cease and desist thing, so I'm worried about how forward to be about it. I wouldn't out Segarule on this, but we sent some private messages, and they said it's up to me on how confidential to go with this. It's exciting, and my goal was to make it as accurate as possible to the original game. So, while unemployed in 2020, I learned Z80 and 6502 assembly, the inner workings of the console in question and the SMS, and just went for it.

At this point, my checklist of things to do is

1. Finish the sound. The other system's sound chip is really nice in doing stuff you have to do in software on the SMS.

2. Fix odd glitches that I made while optimizing stuff for speed.

3. Do more optimizing, and go back to #2 whenever I accidentally break stuff again, and

4. The big one....sprite graphics. The other console's graphics chip having the ability to flip sprite tiles makes things difficult, but I have a plan for that!

5. Either implement some vertical scrolling that works, or scale everything to work in 256x192, since my goal was to make the most accurate port, and work from there. I didn't know when I started that only a small subset of SMS VDPs could do 256x224.

6. If anyone in this thread can give me a good reason to say what game it is without being worried before it's in a state closer to done than it is, I'm all ears.

while Green Beret is clearly a conversion of the game, probably the NES version.


The arcade, the assets where ported from the arcade version, to be exact. If you check them, you will find they are perfect for the conversion, the number of colors, sprites and number of tiles of the stages make them almost perfect to do the translation to the sms hardware.

The screens and bosses are from the arcade, too. I never played the nes version, but spent many time & cash with the arcade.

I tested the game and it is really amazing. The sound effects are closest to original. I hope that @Jabberwocky can turn it compatible with SMS 1 resolutions. I think that Emulicious will give to him everything necessary to simulate the 1st revision EDIT -(my fault. I would want say "first model").
Keep up.
PS: Im sure that members here will give all support in technical questions if you need of it.

Don't say anything until it's released.
Once it will be, IF you'll get a C&D from BigN, you will have to pull it to comply, but it will be too late. ;)

That was more-or-less my plan. :). I wish I could keep everybody updated on progress, but it is what it is. Once it's out there, the internet does not forget!

I just wanted to comment that this is in fact false. The second revision of the VDP chip is likely more widespread than the first one, so much so that many 'first model' SMS have the updated chip, especially in Europe, and every Game Gear also supports this resolution in SMS mode. But indeed it's true that not every SMS can use 256x244, and unfortunately also the Genesis/MegaDrive doesn't support that.

At the end of course the choice is yours. If retaining the original resolution is crucial, you should release an SMS-II only game. After all a huge percentage of players will enjoy the game through emulation anyway...

My 2 cents, of course :)

4. The big one....sprite graphics. The other console's graphics chip having the ability to flip sprite tiles makes things difficult, but I have a plan for that!

5. Either implement some vertical scrolling that works, or scale everything to work in 256x192, since my goal was to make the most accurate port, and work from there. I didn't know when I started that only a small subset of SMS VDPs could do 256x224.

6. If anyone in this thread can give me a good reason to say what game it is without being worried before it's in a state closer to done than it is, I'm all ears.


Can verify that it runs great on my sms 2, but is obviously broken on my model 1 sms systems (pal & ntsc-j) due to running in 256x224 mode. I'm deffo excited to see how it progresses :D

IMHO, disregarding certain Eurocentric assertions, I think differently.I don't have prejudice against Europe, as it has been appearing in my country in recent years.
Here, there has been an increasing defense of the idea that European influences have caused harm to the native peoples in America. Even acknowledging certain impositions of cultural norms, I understood that historical cultural exchanges were rich (in other cases, detrimental).

I try to imagine a game that would run exclusively on a Brazilian SMS.If I knew the programmer, I would never advise against making it more compatible with other res modes.
Why? Because I believe that people can benefit from everything.If a game can be enjoyed by a greater number of people, that's really cool.
I will encourage the developer as much as possible to produce a game for the widest audience. If, at the end of all processes and efforts, it's not possible, then with much sadness, I will lower my hope and optimism. But I will applaud what has been done.

Meu 1 real.

I just wanted to comment that this is in fact false. The second revision of the VDP chip is likely more widespread than the first one, so much so that many 'first model' SMS have the updated chip, especially in Europe, and every Game Gear also supports this resolution in SMS mode. But indeed it's true that not every SMS can use 256x244, and unfortunately also the Genesis/MegaDrive doesn't support that.

At the end of course the choice is yours. If retaining the original resolution is crucial, you should release an SMS-II only game. After all a huge percentage of players will enjoy the game through emulation anyway...

My 2 cents, of course :)


Yeah. It doesn't work on my own console. I have a North American model 1 with Snail Maze as the built-in game, and it definitely has the VDP that doesn't support those resolutions. I thought I read somewhere that only European PAL SMS2s had them, but interesting if that's not true. Good to know that's not exactly true!

As far as the rest, my goal is for it to be as faithful to the original as possible when released, but might work on other version in the future. As far as being able to release them, that becomes more difficult, I would guess.

So I would suggest you to even consider a double release - if the extended resolution works just perfectly but you still want to support the original resolution too (which I totally support, let's be clear!) you'll be everyone's hero.

Ideally, that's the plan. Thanks everyone for being supportive and understanding why I'm not naming the game. I've always figured that a Game Gear port would be on the table, so adding a vertical scrolling engine (but one that keeps the ground visible using horizontal interrupts) might be a decent solution that would allow the port to work on any Master System (and the Genesis/MD too).

When you mean horizontal interrupts, do you want to update vertical scroll during a scanline? this trick doesn't work on the Master System VDP due to vscroll value being latched at the begining of the frame

Yeah, that's what I meant, but I hadn't tested it. Thanks for letting me know. I guess I'll have to come up with another solution.

@haroldoop See this video

He released a new version of planet X.
There is explained the difficulties in develop the game. The algorithm for movements, the color limitations with RAM and not possibility in port it for systems < 4Mhz.

Hello, I wish these games were ported to the SMS or/and SGG before I suggest to clarify whether the originals games in list are official or homebrew, so avoid misunderstandings, and how the conversions/ports are being made source code available or recreation.

This is Ultimate Mortal Kombat 3 for the Gameboy/Gameboy Color by Z80artist this homebrew runs smooth maybe 60fps, It could be ported to the SGG and for the SMS using the 6button MD controller as is compatible with Super GB 2players with SNES controllers.




Ported to the MSX2 Ghosts'n Goblins is a recreation of the Arcade by Assembler It seems is using a special graphic card to do so, and a version is running in the Z80.
