Title: MAME CHD issue
Post by: RetroScotty on January 17, 2015, 12:24:46 pm
Hi Guys,

In need of some help!

I've had MAME working with CHDs for a few years now, with no issues.

I decided today to update MAME to 157, it installed and worked fine except the CHD games. I keep getting the "ROM or CHD Missing" error.

Here's what I have tried so far:
*Downloaded newer versions of the CHD and Rom
*Tried MAME 149 (same error)
*MAME.ini rom directory is correct
*e.g of locations ROM:\mame\roms\sfrush.zip CHD:\mame\roms\sfrush\sfrush.chd

If you guys have any ideas to try, it would be greatly appreciated!

Many thanks,

Scott

Thanks for the suggestion Louis, didn't work unfortunately.

I also tried with the CHD in the same rom directory and mame directory.

CHDs aren't meant to go in zip files, you can put them there, but it means MAME has to then extract them to memory first.  There are situations where that might be useful (if you want absolutely no disc access on CD based games once MAME has loaded the rom) but it's not really the way it's meant to be done.

For the OP, actually studying the exact error message and posting it would help.

My gut feeling is that you're not reading the message and trying to fix the wrong problem.  More recent versions of MAME use device roms, for example sfrush needs tms32031.bin, in tms32031.zip which is the internal bootstrap code for that CPU.

The messages are explicit, not pasting them exactly helps nobody.

Hey Haze,

That tms32031.zip worked! Looks like I'm gonna need to do some research and see what additional files I need for the other games.

Appreciate the help guys, thanks.
