I'll look into the checksums... there was a tool to generate ' FLUKE' style checksums , that I used a couple of years ago on and it worked... I assume QA has ran them through this algorithm.. I'm 99% sure it's the correct rom revision/s (as its printed on the Label/s) but I could pull and read in..... Outrun is not protected (Turbo Outrun is with an encrypted cpu) , but there is a custom chip that sits on the CPU bus's that handles a few things, However the address and data bus to the rams and roms come straight from the CPU....... Maybe I've chosen something tricky to start with ? I'm just hoping that its noob finger trouble and lack of understanding thats the isssue here, lol !!

Now these are 64k Roms x 8 bits each...... but I'm unable to run ROM tests here..... It fails on checksum....!!!!!!!!!!
Initial thoughts: Are QuarterArcade's checksum values verified? Different ROM rev perhaps? Any copy protection used on OutRun?
