MiSTer FPGA Forum

I just managed to get the Arcade cores working a few days ago by changing my update_all settings to include Arcade ROMs. I tried a few out and all was fine until I got to Ghosts 'n Goblins, then I just get this on screen:

RAM OK

ROM CHECK
ROM NO GOOD

I can't start the game or do anything other than press the button to view the core credits, which does work.

I tried deleting the .zip file containing the ROM data from the SD card and then re-running the update_all.sh script but I get the same result.
Ghouls 'n Ghosts seems to work ok. I'm assuming that the ROM is fine as I don't see any threads about 'ROM NO GOOD' on this forum.

Can anybody help?

EDIT: I just tried loading some of the alternative versions. The US and World Set 3 versions both gave the same ROM NO GOOD error. However, the Bootleg and Word Set 2 versions initially both ran and went into demo mode for a few seconds, before the screen went nuts. It just filled with multi coloured flashing garbage. Trying to run those 2 ROM sets again and I then got the ROM NO GOOD error for both.

Jotego is looking into it --> https://github.com/jotego/jtcores/issues/349

Might want to report your issue as well since it's not a crash but the rom can't load. Could possibly be an sdram controller issue or some marginal timing problems.

Ah, in that case it might be because I currently can only see half of my SDRAM. I recently built a MiSTer Multisystem and on the SDRAM board I have an incorrect non-inverter IC. When I get the replacement then that might fix it.

Thanks.

Oh yeah, if that has the wrong IC on it, there is your problem!

Changed the IC and all good now.

Thanks again!
