Hi Shea,
I have downloaded your PiMAME 0.6 Beta 5 and have been impressed with the increase performance of AdvanceMAME. I can now play Street fighter II at full speed on a Model B 256. I am going to test the same setup on a Model B 512 with a Sandisk Ultra 8Gb card rather than Standard Sandisk 8Gb card to see if this also improves performance for games that are still a little slow such as NBA Hangtime.

I have started testing / trying NeoGeo and PCSX_ReARMed but not having any luck yet. I realise you can not help people to find games but could you write an updated list of instructions for people to get started using the PiMAME 0.6 Beta 5. ie

I have tried putting some NeoGeo roms into the /home/pi/roms folder and they are visible in the game list in Neo Geo but when I try to open them i get the following error:
ERROR!
Gngeo Couldn't init GAMENAME:
Parent roms//GAMENAME.zip not found
Maybe the romset you're using is too old

I also tried putting a full .rar game file into the /home/pi/emulators/pcsx_rearmed/bios folder. I have no idea if this is the correct place and if it needs to be unzipped first but could find any instructions on your site. When I load the PCSX emulator I get the following error:

You don't seem to have copied any BIOS files to bios/
while many games....

Thanks for all the work you have done so far.
