CD32 games on A1200?
Dear community,
can you play CD32 games on the A1200? The latter emulation is faster for me so how would I need to configure the chipset etc. so I can boot from CD on the A1200? Maybe via floppy disk (CD bootloader, just like the kickstart disks)? I tend to suspect that this is not possible... Regards, Michael |

There are probably some games that you can run directly from cd and some CD file systems included CD32 emulators iirc.
But the most reliable solution would probably be to find whdload installers for the games you want to run. You wont get any cd audio though. Check here for installers www.whdload.de |

Why would need to emulate A1200 to run the game faster? Any machine can equally be configured to run at ludricious speed in WinUAE

why not just use CD32 mode if from emulation? what's the point of emulating a A1200 to play CD32 without audio, with possible issues?

Didn't notice this was in the WinUAE forum. If using WinUAE you can just emulate a CD32 and run the games directly from cd

However you can emulate A1200, you install Workbench and then idefix and so you can emulate CD32 inside A1200 (in double emulation), but the speed of CD32 games are identical like you run CD32 games directly from WinUAE quickstart. |

I guess Akiko chip dependant games may cause problems?
Although I have a suspicion the few games that did support Akiko just took advantage when detected? |

Only Wing Commander took advantage of Akiko, I believe. I also believe (I think I read it on here) that actually, even Wing Commander doesn't use Akiko because of an error in the code (i.e. it was supposed to use it, but doesn't).

akiko does c2p through WriteChunkyPixel rom routine, and never called directly in any game. If it's not there, c2p is done by software, which can be faster than CD32 on fastmem-equipped A1200
no fantastic visuals are achieved on CD32 that cannot be done on A1200. The only advantage of CD32 is CD-audio mixed in audio output when playing (for games that provide CD music) |

At least You must boot from a floppy which has a device CD0 to mount and the pass the boot to it.
Even if you could create a Kickstart file with a cd.device there are many variables to take into account, such as the connection, IDE, SCSI, PCMCIA, the number of drives, etc... In reality, we would need software in the ROM that tries to guess everything by interrogating the various devices and checking that there is a bootable CD from which to boot. So, the minimal soluton is a little floppy disk, and keep in mind that loading a device from floppy disk takes up memory, so goodbye to the 2MB of free chips. |

I created a booteable floppy disk long time ago for winuae to emulate the CD32 and play CD32 games
I created it using the idefix97 v3.5 package which contain the CD32 emulator to make it work make sure you check uaescsi.device option in winuae works fine using real CD32 games and a real DVD or CD so here is the floppy disk, report if works on your computer |

Although it doesn't seem to work with emulated CD (cue+bin), see below... any hints? (Using A1200 Quickstart+uaescsi.device; DOS Device is "CD" - when using "CD0" a second window pops up: "Can't open uaescsi.device unit 0") Last edited by Michael Doma; 02 March 2024 at 19:48. |

Problem solved!
Actually, you don't even have to add a drive to the list. Just need to select the image file and then tick "CDFS automount CD/DVD drives" - et voilà! Thank you so much, stx! EDIT: Ticking uaescsi.device is not needed for CD images. Last edited by Michael Doma; 02 March 2024 at 20:15. |

This explains a lot. I had a Zappo CD-ROM PCMCIA that allowed CD32 games to run using a bootdisk. It claimed to offer 'Virtual Akiko' support, though I guess this is nonsense.

also please note that if you make a winuae config with a 040 cpu then you can use the option called 68040.library, this will speedup some games as Alien breed 3d, Frontier etc btw, Here is the CD32 emu documentation,copy it to the floppy |

Thanks! And I think I found a "bug": CD audio isn't played when a CDTV game is booted (Sim City). Audio works with direct CDTV emulation in WinUAE, but not via CD32emulator. I have selected the CUE file as image and there are separate WAV files for each audio track.
