Hey guys!!!

Thanks and enjoy this new Sonic Triple Trouble conversion, I had a lot of fun creating this conversion.

And why not the last conversion made by Revo from Off The Wall

It's nice to read that you thank us for our work, and for all the effort to turn the majority of exclusive games that Sega created for Game Gear once abandoned the development of new Master System games.

It's a didactic hobbie, let's make it fun ;)

Off the Wall [Proto] v0.42

- ''for play on the sega game gear'' line deleted from title screen.
- background is always black now (no more garbage screen).

After playing the game a little, I don't think that I'm gonna adapt any color manually, the playground is little strange for me, but it's actually the same feeling on the GG version.

If someone want to adapt start button somewhere else, he's more than welcome to do it.

I think they messed the GG version of Off The Wall. If they had removed 1 tile from the board they could have make the blocks 6x6 pixels and removed the UI. I presume it's barely playable on a real GG as it stands.

Hello!!!

I implemented a new function working for games can use Megadrive Pad or Master System Pads if "START" is frequently used, for example RPG games and if rom is not full

For default game is running with megadrive pad, then if you want to play with master system pad, then push master system Pause Button, then it switch MS Pads

Example:

Megadrive PAD Plugged

0.- Init game
1.- Play game normally, START will be START Button

Master System PADS Plugged

0.- Init game
1.- Press PAUSE Button
2.- Play normally, START will be 2nd Player "Down"

(3).- If you press PAUSE you switch to Megadrive PAD
(4).- If you press PAUSE you switch to Master System PADS
(5).- ...

A pleasure to present a "new" ROLE Playing Game to MASTER SYSTEM, many people worked in it

Megami Tensei Gaiden - Last Bible Special V0.6 GG2SMS

- Megadrive or Master System Pads switching with PAUSE Button, START is MD START button or MS 2nd Player "Down" (Default: MD Pad)
- Full palette conversion
- Removed GG ports
- Translation Credits to MrRichard999, SSTranslations (Steven Seehorn), Tom, Helly, Hengki Kusuma Adi, rainponcho
- Game funny playable, remember SRAM needed to store data
- Patch Japanese Rom
- Corrected Checksum

Known "bugs"
- For now intro music is running fast, if possible set console to 50Hz

Seems I had confused it with the original Last Bible.
(the one ported from Game Boy, officially known as Revelations: The Demon Slayer. Though it sounds like Tom might be interested in doing that one too at some point, with a fresh translation as supposedly the official one was very bad.)

Thats awesome.

But why does not more games use the Mega Drive Joypad ?

Like for example, Tails Adventure.
I cant finish the game because it dosent support the Mega Drive Start button . A real shame in my oppinion.

Please, dont forget us Sega Mega Drive users. (especially with an everdrive X3 that has NO SMS pause button )

Please support the Start button on the MD Joypad.

I thought it was possible to detect a Mega Drive pad and avoid the need for separate versions of the patches.

Hello Maxim, detection is not possible, it returns same state $FF if pad is plugged or unplugged, master system or megadrive pad pushing any button always return $FF

But great news, I've got an idea !!!

Simply and easy.

Boot game or reset console with Megadrive Pad "START" button pressed if you want play with Megadrive PAD, if not then Master System Pad

I wrote code and yeah! It is working with Tails Adventures ;)

You could read in Mega Drive mode but discard the second version of the data until it is different from the first, which confirms a Mega Drive pad is present. Radical Rat detects the pad, maybe in a different way: http://www.smspower.org/Homebrew/RadicalRatSMS-SMS maybe you can find out how that works.

Actually you can check if the connected pad is a SMS pad or a MegaDrive pad, and even if it's a 3 or 6 button pad.
See http://segaretro.org/Six_Button_Control_Pad_(Mega_Drive) (note - it isn't perfectly correct!) - the point anyway is to set TH 'high', read the pad, set TH 'low', read again. Now, if 'right' and 'left' are pressed at the same time (impossible on a SMS pad) then it's a MD pad and you can read the state of 'A' and 'Start' button. See this demo I made a while ago.

Woh! I'll try it this night.

When I set TH high sometimes it is returning $D3, I saw then LEFT-RIGHT pushed, but not all times.

If set TH high, read, set TH low, read and it is different $FF then yeah!!!!

It would be very easy to implement to patch.

Thankyou sverx and Maxim

LD A, $F5
OUT ($3F), A
IN A, ($DC)
LD A, $C5
OUT ($3F), A
IN A, ($DC)

IF Megadrive Pad is plugged THEN it returns $F3 !!!!!

IT IS FANTASTIC !!!!!

I added a "beep" sound if it detects megadrive pad for let you know game detected MD pad and is running in this mode. (Only when game boots)

I tested MM on my Nomad and it works. It's pretty hard to play due to sprite border issues, but I imagine those are an inevitable part of the SMS conversion.

A comment about MD pads detection.

MD pad returns 00 in Right and Left bits when TH line is 0. To detect 6 button pad you'll have to do few more TH cycles and it'll put zeros into some other bits :

TH=1 x1CBRLDU
TH=0 x0SA00DU <- 3 button pad detected
TH=1 x1CBRLDU
TH=0 x0SA00DU
TH=1 x1CBRLDU
TH=0 x0SA0000 <- 6 button pad detected
TH=1 x1CBMXYZ
TH=0 x0SA1111
TH=1 x1CBxxxx <- undefined, this cycle is needed to end 6 button access or the pad won't return more 6button values next time. 6 button values can only be read once per frame.

Hi people!

smokemonster thanks for testing. You get master system resolution with a game with game gear resolution ;)

Revo, I tested 0.53 and 0.55 and title screen colors does not differ, I don't change any palette cicle in this update, I only implemented autodetection

TmEE thanks for info, I tested MD 6 button pad in Emulicious and it is working ok, we only need "START" button

This topic if full of great conversions but, man, I sometimes have to come back to it just to see what the button combination for starting a game is...


They all start by either hitting the 1 or 2 buttons on the first controller, or the down arrow on the second controller. Also, all are referenced in the hacks section.


Hey guys, I am new here to this website and need some help with a Master System port posted here. I can't seem to get the Tails' Skypatrol Master System port to start when at the title screen. I can skip the intro sequence, but can't actually start the game. I tried pressing the 1 and 2 buttons as well as the down on the second controller that I mapped in Kega Fusion like the person said in the quote above, but the game still doesn't take me to the Training Area Zone. Can someone help me please? Thanks! :-)

Shining Force II - The Sword of Hajya V1.1 GG2SMS

- Master Everdrive compatible
- START mapped to Megadrive pad "Start" button OR Master System pads Player 2 "Down"
- Deleted upper garbage in animations, really this game is getting very very low garbage

Conversion by BcnAbel76


For save game with Master Everdrive:
(THIS IS NOT A BUG GAME, for now Everdrive OS7 or OS8 is not correctly autosaving and delete file)


- You need OS V5 version!!!
- Load manually SRAM, first time you can for example create SRAM file in Emulicious, only entering your name, then save it into SD folder SAVES
- Load game and continue in menu your data progress
- For save, remember you need EGRESS magic to enter save data and advance a bit in game history. When you see "Your adventure has been saved" then switch off system, if you continue your data will be corrupted !!!
- Init system and go to Tools/Save SRAM, select your backup file to SAVE your progress
- Next time you can continue without problems


Awesome. Is it possible to make this work on a Mega Everdrive? When I try playing it the screen shakes and then it crashes.

lennykinds009:

Do you try to run game in Emulicious???
Try to check "checksum" your rom for determinate if it was well patched

chrisw80:

Basically you need to load/save SRAM manually, I don't know about OS version in MegaEverdrive is doing it manually

I just signed up to this forum to say thank you to everyone for the work on these patches. I've been looking for a good way to play gg games on a tv for a while, and just picked up a mega everdrive with testing these conversions out as one of the main reasons for doing so.

I'm particularly interested in the RPGs for the system (Sylvan Tale, Moldorian, etc) and would be more than happy to provide a J>E translation to go with a fully playable SMS conversion for any of them. (I actually translate stuff for a living.) So anyone who has the necessary skill and is interested feel free to get in touch!

Thanks again!

Frogger also need an update to work on real hardware.
GG ports at $7AA ; $3561 and $37DD


Wow, so I did miss those (the latter 2 port writes). Sorry. I guess at the time I oddly didn't catch "out(c),a" style instructions. :(


Was the updated patch released anywhere? This is my all time favourite game and I would love to be able to play it on rh.
