Super GameBoy like for PS1 !

Post by Orion_ » October 3rd, 2014, 8:02 pm

I went to Japan recently and I got this "Super Gameboy" like for Ps1 ! (found in super potato shop)
It plugs on the parallel port and you can insert any gameboy cartridge.
Unfortunately, most of the games I tried aren't working :(
And the only one I got working is running a bit slow.
It seems like it only supports 32k games. (so even "super mario land" isn't working)
There is a list of the supported games, but it's all in japanese.

2018: I finally managed to dump the rom of this thing:

I've seen this before, but I didn't know it was that bad. I have never owned one so I wouldn't know anyhow.
Would you be able to open it up and take photos of the PCB so we can see what it's doing?
I doubt it has a Z80 in there... if it did, the compatibility would be much higher.

well, not much to see, a 256k eeprom, and a PAL chip (?)
nothing on the other side.
I guess a much better emulator could be made, but well, who will put that much time in doing one today :/

The 256K ROM will contain the emulation code and the background that comes up with the colourful gouraud (possibly flat) shaded background. The PAL ('Programmable Array Logic'. Not 'Phase Alternating Line' like the TV PAL/NTSC you're thinking of :P) would contain glue logic that links the Gameboy edge connector to the PSX's. Most likely, it copies the Gameboy ROM into the PSX's RAM (you can check this with a PSX memory editor) as well as copying the emulation PS-EXE. I can't make out what the little SOIC-8 package is. You say nothing is on the other side, but there should be more traces coming from the Gameboy edge connector.

Overall, it's a piece of shit junk I'm afraid. Very cheap build quality.
The source code behind it would be interesting to read though considering the R3000 should be good at interpreting the Z80. I bet NO$CASH with his assembly knowledge could pull it off overnight (also considering he made his own GB emulator) :praise

If the games are running slow, you could always try overclocking your PSX (don't do it to the Yaroze though. Use an old junk PSX) ;)

I totally agree!If there is a way to read that 256K ROM eeprom, then we could make a working gb emulator!

The ROM would contain binary. Not source (unless they actually left it in there :lol:).

if you have an utility I can run on the psx to dump the AR rom then I can do it.
the only problem is how to output the data... I have the yaroze serial cable, or maybe write it in multiples parts on memorycard...

Funny. I always thought there would be more to it than what the cart contains...

I have an idea though.
If that cart only places PSX-EXE and GB ROM into RAM then after a reset it should still stay in memory.
I could modify my BIOS dumper to dump any part of the RAM to serial port and use BIOSGet to fetch that data.

Then we can check out and see if we can find the EXE. I'll assume they use a standard initial address
so I'll place my dumper near the end of the address space...
You will probably need to hot unplug that cartridge on reset so it doesn't auto start, I hope that it doesn't bether you.

Let me know if you are interested.

I found it on Amazon for a low price. I'm curious to try it.

Is there anything similar, that could handle NES or SNES-games ?

Yes. For NES games you can use "It Might Be Nes".

Okay, good to know. I did find some emulators for PS1 to play NES-games, but it would be a jackpot to get SNES-emulator for PS1. Been a big fan of the SNES since childhood.

The Snes roms are at the limit of the RAM of the playstation . I think it's hard work.

How about adding more RAM for Playstation ? Or is it more complicated than that ?

It's already been done and it provides a maximum of 8MB.
Though, it's actually possible to get 16MB with some BIOS hacks.

Testing gb roms
I discovered that adding the game to the end of the rom works
using copy /b command

i tested in no$psx emulator,32 kb games work fine
but games with bigger 32 kb not work,some using real cartridge work
for example the game Game & Watch Gallery 1 (262 kb) work fine on the real cartridge + psx console
using this method does not work in no$psx

Image

About of Rebound Mission:
the internal game Rebound Mission is based on the game Poke Mission 97
Poke Mission 97 is a 32 kb game
It would be interesting to replace this gb rom with another better game for example tetrix or dr mario

Credits of the emulator (i found this text in the rom):

CREDITS
PSX Code: Alex Edge
Damon Barwin
Hardware: Roy Harding
Resource: Pascal Felber
Rebound: Anders Granlund
Help: Anonymous 2

Thanks goes out to all the people
who have helped in the creation of
the Gameboy and emulator scenes.
Lookout for new and better things
from us in the near future...

WOW!
After two years what an unexpected surprise!
Thank you guys for sharing all these informations and files!

I think we should better find a way for the emulator to load files straight from a folder.
