Post subject: MSX-Audio causes freezing in two Compile games
Reply with quote

I have made most of compile games working w/ MSX-Audio enabled(via FS-CA1).
But there are two Compile games which freeze during boot-up when I boot them w/ FS-CA1

They are :
Gorby's Pipeline (Japan)
Madou Monogatari 1-2-3 (Japan)

The screen says "loading PIPELINE" for Gorby and "loading DS #11" for Madou, then freezes up...

The disks are from Tosec Set and they works very well without FS-CA1, so the disk images should not have any problem in themselves.

Do you have tried to de-activate the second drive by pressing on LeftCtrl when booting with the game disk in first drive ?

It looks like there's something missing in the MSX-AUDIO emulation.

I've found a solution for Gorby's Pipeline : try the cracked version (SMA). You need to process as following :
- boot with nothing (!) in the slots and drives
- when you are in MSX-BASIC, insert the game disk
- type POKE -54,35:POKE&HF346,1:_SYSTEM and press on RETURN

I'll check later Madou Monogatari 1-2-3.

For info : the first poke simulates the presence of the Panasonic cartridge. Normally, it requires the Music Module or the Toshiba module.

Actually, you can try sucessfully the same trick with the official versions of both games. I still don't know why the using of the Panasonic rom leads to an hanging, maybe there's a conflict between the rom and our MSX-AUDIO implementation.

Confirmed, but we (including openMSX guys) were unable to fix it. Better luck later, if someone gets their hands on an FS-CA1 and examines its guts.

Jorito has done a few tests with his FS-CA1. This problem (at least for Gorby Pipeline) happens on a real MSX too. Smile

it's the same bug in both games, caused by the assumption the BIOS is switched on during the check...
