RNC IDE CD32 loader
I'm guessing that this isn't supported by WinUAE yet?
titles like James Pond 3, Pierre le Chef have it. |

Lots of games have it, it was a good way of grabbing as much memory as possible on CD32 because the DOS system takes a lot of memory up.

I suspect that this IDE CD32 code expects a very restricted ISO format that I'm unable to reproduce with MasterISO. |

It's not a problem of ripping, it's a problem of building the correct image format within a compilation. It's easy to rip the ISO and burn a 1:1 copy and it works, but adding other games on a CD32 bootable CD means rebuilding the ISO and that's where it fails to work. CloneCD won't do anything about it (specially because the CD32.TM file must be included in a special boot location to make it boot). |

I also gave James Pond 3 another stab with a quick startup-sequence to see if it would work out of another directory.
CD32:C/DevRen CD0: xxx: CD32:C/Assign CD0: CD32:Games/JamesPond3CD32 CD CD0: CD32:C/MoveSYS "" C:SetPatch >NIL: C:FreeAnimation >NIL: C:Assign >NIL: ENV: Ram: C:CDGSXL CDXL/intro.cdxl blit sdbl xlspeed 150 noxleec multipal lmbabort rmbabort fireabort nopointer patchopenwb ;C:CDGSXL CDXL/intro.cdxl dosxl blit sdbl xlspeed 150 multipal lmbabort rmbabort fireabort nopointer patchopenwb Loader >NIL: Of course i got Loading Error 1, please reboot". I built the image with ISOCD using the CD32.TM from the Official CD32 Developers Kit. What i did notice however is in the loader binary i found some readable areas which looked like this. CD0: CODE.BIN RESGFX.BIN Unable to setup CD. Reboot me! Load Error(1). Please reboot.. Load Error(2). Please reboot.. Please wait while I load. Yup... still loading... Nearly finished... freeanim.library graphics.library This suggests to me that it is hardcoded for CD0: and if it does take over the OS like previously suggested then i would guess any settings done before the loader starts would go up in smoke anyway. To confirm this i put CODE.BIN and RESGFX.BIN in the root of the cd "CD0:" and guess what? It works. At least until it asks for the next file which needs to be in the root and so on until it requires another. |

Maybe I'm just being slow, but I can't see exactly what you have discovered here??

That the game must be run from the root directory of the cd.
![]() If the path is changed it will have to be something of equal length or the binary will be knackered. |

You could always disassemble the loader and see what is happening

I am already working on that with my own experiments
![]() I also have my crack of Strider running with the RNC CD32 loader and a few other small programs... it's just something I'm slowly working on in my spare time ![]() |

And rebuilding the ISO using MasterISO even if you keep all the files makes an unusable disk (loading error please reboot), although it works with most of CD32 games/compilation. Official commodore ISO building tools seems required here, but assigns of course don't work! |

I've always used ISOBuild and CD32.TM from the 2.1 Developer CD (I then burn the ISO on my PC) and it's always made working discs for me... So I can't really comment on other ISO tools.
@jotd: Yes, that would be cool to see what you have of the loader - I'll send you a PM ![]() @redblade: Yep, the CD32.TM gets burnt onto the disc in a fixed place and is not seen as a file. But that wouldn't be them problem here because then the game wouldn't boot at all... |
