CD32 Cubo

Cubo CD32 is a regular CD32 hacked to handle the coin input. At least 8 games are known to exist on this h/w (6 of them are in MAME). You can boot the games into the attract mode in WinUAE as CD32 ones, but you won't be able to insert coin or enter the service mode, since they are unmapped.

[Toni Wilen]

They are mapped, try pressing all CD32 buttons.. (FFW = Numpad - by default)

[F1ReB4LL]

Nope, nothing. Are you sure they are mapped to the CD32 joypad buttons? According to http://ninjaw.ifrance.com/cd32/cubo/ , it has a custom controller card with the coin input and some additional dip switches.

[Toni Wilen]

Two randomly chosen games (Harem Challenge and Laser Quiz) can be played without problems. FFW = insert coin here.

Don't know about possible service mode switches. (there is absolutely nothing Cubo specific in WinUAE, Cubo games just appeared to work so I didn't bother with it)

[F1ReB4LL]

I have only Candy Puzzle, doesn't work there. Maybe, FFW is one of the service buttons, not the coin input itself.

i found odeon twister 2. these dumps were done in mame's chd format. i can insert the chd image, but stalled on some cd32-menu-screen.
Toni: next to cubo "emulation", do you think there will be chd support, once in winuae?

[Toni Wilen]

AFAIK there still isn't full source without license issues. I am not going to write one myself.

chdman.exe probably supports conversion to some supported format.

[emufan]

codesearch revealed some related file:
chd related files from mame sourcetree
cannot say what it mean. does it fit somehow to winuae?
maybe chdman is the way to go. with chd support, we could use, whats already preserved.

Hi Toni,

All of the files involved in CHD are dual-licensed as plain MIT/no-credit BSD to enable usage by other emulators. If any files were missed, please let us know and we can correct the situation.

Thanks!

emufan,

That is not the main MAME code, that's a fork/port to the Nintendo Wii. Current MAME source is browsable at http://git.redump.net/mame/

Thanks,

[emufan]

thank you for joining Mr. R. Belmont.
what i get from your posting here, it seems possible to have chd support in winuae. that is good news.
thanks to the mame team for all your work you have done
ps: i bookmark the correct source url now - i too fixed the link above.

[Toni Wilen]

No wonder I never found anything, very well hidden in deep directory structure. (I did find chdman sources but it didn't look right)

I guess with some copy/pasting it can be done. I am not going to include anything else than low level CD toc/subchannel/read functions, I don't need any sector conversion or any other helper functions.

First problem: LzmaDec_Allocate_MAME() in chdcodec.c. Does this need some special Lzma SDK? (and why?)

ADDED: It is also quite impossible to disable compression support without big modifications.

Hi Toni,

That function is simply to glue LZMA to MAME's internal memory manager, which tracks leaks and such. The actual compression is completely standard LZMA and you can use the stock LZMA SDK.

I don't think so. Check the function yourself in lib/lib7z/LzmaDec.c, there is also interesting comment.

Anyway, I got zlib compressed chd working already. (no audio tracks or subchannel support yet but soon)

EDIT: audio tracks work too (only zlib tested, don't have other test images)

EDIT2: zlib, lzma, flac tested and confirmed working (with LzmaDec_Allocate_MAME added to LzmaDec.c). Subchannels should work but not tested because chdman does not seem to accept .ccd and all my CD+G test images are .ccd.

Do you have a test build?

Nice job, Toni. : )

My first test was the CD32 version of Pinball Fantasies and it works.

Great work, Toni!

Do you have documentation for .ccd? That is the main reason chdman doesn't accept it at this time.
