 Sega 8-bit winter of dumps Part 2: 4 PAK All Action

We're back with a long, long awaited dump.
4 PAK All Action for the Master System, published in small quantities in Australia by HES in 1995. This 8 megabit multi-game cartridges contains 4 original Korean games developed for the Master System by Open. Some of them were previously known, but the versions in 4 PAK All Action were localized for an English-speaking audience and bear different names. Let's have a look at our four games..  
Adventure Kid ! A clear unlicensed clone of later Adventure Island games (iterations of Wonder Boy) using a legacy SG-1000 video mode (not smooth scrolling alas, but the game plays relatively well).  
Power Block ! Previously known as Suho Jeonsa (수호전사), this is its English localisation.  
Twin Mouse ! An original platformer.  
Cave Dude ! Previously known as Toto World 3 (토토 월드３), also an English localization of the game. We hope you'll be having fun trying those odd Korean-developed games released in Australia. Please note that the 4 PAK All Action cartridge relies on unusual mapper hardware and is only supported by a few emulators so far (MEKA and MESS). Go on and talk to your favorite emulator author to get it supported in other emulators! |

I thought this dump would never arrive!
By the way, I think Adventure Kid is actually a clone of Adventure Island 2 or 3. The dinosaur riding gives it away. |

Hmm, can't seem to get this working on Meka 0.73 or 0.80. It goes to the game selection screen and resets once you have selected a game.
Edit: My version of Meka was a tad out of date, got it working now |

Wow! That Adventure Kid is pretty decent.
Hope to find the MSX versions some time.... |

The mapper as I reverse engineered it is:
Write xx to 3FFE: map bank (xx)&maxbankmask to memory slot in 0000-3FFF region
Write yy to 7FFF: map bank (yy)&maxbankmask to memory slot in 4000-7FFF region Write zz to BFFF: map bank ((xx&0x30)+(zz))&maxbankmask to memory slot in 8000-BFFF region *EDIT* there was a typo above before The code is on MEKA svn, file mapper.c grep for Write_Mapper_SMS_4PakAllAction |

Nothing particular, I've been processing a long queue of unusual cartridges and in the last 3 years didn't have access to that one in particular. Last time I tried to dump this was probably 6-7 years ago and then it would fail reading stable data with my SMS Reader. |

| and, to be precise, the dump works in MESS by using either the Japanese SMS driver (smsj) or the Korean one (sms2kr) | |

In RetroCopy with the BIOS enabled this game isn't detected in the cartridge slot.
This dump doesn't look "valid" to me. A lot of FF filling cart space and the inability for this game to function on a real system due to lack of checksum and TMR SEGA text? If the game was released in the Australian region I would think it would need to comply with the local SMS and its BIOS? :) |

There could be an issue with the header, I will look into that this week-end.
As for the ROM chip being 1 MB i assume there's lot of unused space though. |

I just thought a bit of the data looked "too repeated" but who knows. :)
Thanks for the dump bock, interesting cartridge to dump and have in a collection now. |

| is the header checked by the Korean BIOS? I never investigated exactly which routines are active in which BIOS (judge had made them all work long before I started fiddling with SMS ;)...), but the dump definitely work with the Samsung BIOS so either the check is not enabled or the header is not so corrupted. | |

| Japanese and Korean systems don't check the header. | |

Just to follow up on Maxim's post, this game was apparently only released in the Australian market and all its machines had a BIOS which checked the header. I guess the bigger question is if the header isn't dumped correctly what else is missing? Can't really be sure until Bock does some investigation I guess. |

I don't have the exact details off-hand but I recall that 4 PAK All Action doesn't work on all types of SMS1/SMS2 consoles.
I am toying with the cartridge now and cannot find a TMR SEGA so far so I will keep trying things. Page 1 to 15 are basically empty they contains: Page+0000 : XOR A Page+0001 : LD (3FFE), A Which reset the mapper. Presumably because the mapper has no stable reset mechanism? After the paging is completion following instruction would execute the normal code in Page 0. # smspage "4 PAK All Action (AU).sms"

Attached are pictures of the board. Consider the fact that the 'TMR SEGA' is a measure against unlicensed game releases because including that string in your cartridge would be infriguing Sega trademark somehow?
So, as much as I hate making up random theories with no explanation, do you think there could be a way the cartridge could hijack ROM/RAM code in some way? Chipsets left to rigjt: GS 9436 GD74LS74A GS 9441 GD74LS138 AL (vertically) P9348 GAL20V8-25LNC GoldStar GD74LS670 9314 KOREA DIS-SG4-1 (rom chip)

I already had been thinking about a "hijack" system. How did you dump the game? Was it from inside the SMS or just pulling it off the ROMs?
If it's inside the SMS you should be getting the TMR SEGA bit when you read it, otherwise the BIOS would also fail it? |

I confirmed the above dump on SMS Reader reading from 0000-3FFF region using register 3FFE and reading from 8000-BFFF region using register BFFF as well.
Reading from the 4000-7FFF region using register 7FFF would always return me Page 1 (Sum:3FBA14, CRC:FCEA8F7F) for any value >= 1 for some reason, so unless I made a mistake or missed on some of mapper behavior. Connected to a JSMS and reading 0000-7FFF directly without writing to any mapper would return me Page 1 (Sum:3FBA14, CRC:FCEA8F7F) in both 16kb slots. This is what the BIOS would see I imagine. I'll investigate more later but maybe you guys can get additional information from the board pictures.? |

|
| One thing that might be possible: the cart could take over the bus and nobble the BIOS checks in RAM - maybe just writing a jump, thereby never including the TMR SEGA string, but it would be very specific to the BIOS revisions it would work with. Maybe it could do this with a timer or based on some detection of the CPU accesses to the cart? | |

Testing the cartridge on different consoles:
SMS1 1.3 BIOS : Software Error SMS1 Hang On : Works SMS1 Hang On & Safari Hunt BIOS : Works SMS1 Missile Defense 3-D : Missile Defense runs (no software error) SMS2 Alex Kidd : Works SMS2 Sonic The Hedgehog : Software Error |

Being an 8Megabit cart I wouldn't expect it to work on the earlier consoles, as with Street Fighter and a few other Tec Toy games. I'm surprised it worked on a Hang On only model, all the ones I've had refuse a 8meg cart. |

Must be that case in Australia, then. :) I understand it right, Sega vs. Accolade said such a protection measure wouldn't hold in the US, decided like three years earlier (it ruled that trademark infringement was allowed if it was the only means of access to hardware in order to release legal unlicensed software, nullifying the Genesis equivalent of TMR SEGA). |

| If I was developping an unlicensed cartridge and I found a way to bypass using the official "unlocking" scheme then I would do it anyway. | |

It also works on the SMS1 with Alex Kidd bios, which I am assuming is the same as the SMS2 Alex Kidd (still surprised me when I got that SMS1 and Alex Kidd was on it!)
It is interesting to compare the palette differences between the game viewed on real hardware and on the emulator. On real hardware it is much darker, check out the little guy standing on the map!

| The Mark III and SMS have a darker palette than a SG-1000/SG-1000 II/SC-3000 when playing legacy video mode. | |

Well it is good to see it closer to the way it was originally intended (^_^)
Check out the sky color in the first shot, it is cyan on real hardware and sky blue on the emulator. I wonder if it would be possible to rip out the Adventure Kid code and get it working on an MSX emulator? Edit: Looks like your dump of Wonsiin works on the MSX: http://www.msxposse.com/site/forum/viewtopic.php?p=24327&sid=68b49b53fdd995b... Of course this situation is more difficult because the game is on a multi-cart. |

Can you give the Missile Defense one another try? It's odd that it'd fail there but not elsewhere, as its BIOS routines are basically identical to the AKMW BIOS. SOFTWARE ERROR only appears if the TMR SEGA is found, so that's working (or, at least, passing) on all systems but the difference is with either the checksum or region code. If the game was able to alter the BIOS code then it'd make sense to skip the whole lot rather than individually altering the various checks, so I think my earlier idea is unlikely to be the case. |

LogBomber: as Adventure Kid was likely intented for MSX1 system first its intended color are more like those you would see on most emulators.
However it is true that emulators should give the choice to use the crappy SMS palette as an option. If you extract 128 KB of data from after the first 256 KB you'll get a standalone Adventure Kid. The mapper code may requires hacking thought. I'll try the Missile Defense 3-D BIOS again sorry. |

Ok I have extracted the 128k game, and tested the attached .rom file on blueMSX and renamed it to .sg and tested it on Meka (which works with Wonsiin on either) and as you thought it doesn't work. Any pointers on how to hack it to sort out the mapper? |

| The fix is easy to do to run with a SMS emulator but I won't do it as it is wouldn't be useful. I don't know enough about available MSX1 mappers/hardware. Someone who knows can easily reverse engineer it using MEKA debugger. Or you can BlueMSX people if they want to support it. | |

| Forgive my ignorance, but are you saying the emulator has to be changed to run the rom, or the rom can be hacked to run in the emulator? | |
|

| Both ways are possible. Changing the emulator is more accurate. Changing the ROM possible if MSX1 has similar mappers as SMS ones which I think it does. | |

| The image seems to have a proper MSX header (starting with AB at 0x4000 when loaded in MSX emulator) and the right ports. But the mapper seems to be the problem. | |

Thanks Zipper. If anyone is interested I have started a topic to see if any of the MSX guys will help, here:

Been examining the board pics, here's some numbers written all over them to say what goes where. It's messy but it might save someone some work. Also tracing hidden areas, dunno. Maybe the GAL could be dumped for further investigation.

Forgive me if this is a redundant question based on other conversations already happening, but:
I know Adventure Kid won't run on a Genesis, but for the other three games, would it be possible to extract them so they could be run on a flashcart? If so, would there be some kind of relatively straightforward processing required to make it work (i.e. take everything from 0xQ to 0xR, and then XOR every fourth byte or something)? |

We managed to get Adventure Kid working on the MSX for anyone that is interested, just check the forum link a couple of posts back.
@goldenband: The Korean Toto World 3 (Cave Dude) and Suho Jeonsa (Power Block) roms are available, and they will probably work on the Genesis with a SMS converter. No doubt Twin Mouse would be a bit trickier, but Cave Dude and Power Block are the better SMS games on the cart anyway. |

| Twin Mouse is kinda weird... it has the two different characters, but the boy seems to have no advantage at all, while the girl can glide downwards slowly from jumps. | |

Yeah, I'm pretty sure I've played one or both on my Everdrive, especially Toto World 3. Mainly I'd just like to play them in English, and also I was curious if Cave Dude's music is as completely messed up (obvious programming errors) as Toto World 3's is. |

| The sound seems badly broken. If possible try to avoid posting a bunch of broken roms publicly to reduce confusion. Get it done and tested then post it would be my recommendation :) | |

| Cave Dude was just an after thought, it was late and I didn't realize the sound was broken. | |
