Neogeo stock at decryption #60

Closed Levrault closed 5 years ago

Levrault commented 5 years ago

Hi,

I got the following issue on the pocketgo with the firmware 1.1. Whenever I try to play some NeoGeo game, the console tries to decrypting it but get stock a 50% every time. I can't quit this state, I can only power off the console.

Is there something I'm doing wrong? The ROMs were working on my retropie.

I'm stuck too when decrypting metal slug 3,4 and 5, senguko 3.

Levrault commented 5 years ago

I think I get what the issue is. If the Rom is larger than 40mo, the pocketgo will not decrypt it. I don't know if this is a material issue or not.

Are you using the right roms from MAME 0.128 romset?

Levrault commented 5 years ago

Hmmm, it's possible that Garou and Metal Slug are all using a more recent MAME. But I thought they just need to be compatible with the good version of FBA?

TriForceX commented 5 years ago

If you are using GnGeo emulator the roms need to be from MAME 0.128 romset If you are using FBA-A320 emulator the roms need to be from 0.2.96.86 FBA romset

it is not recommended to use other romset since the emulator probably will not read them properly.
