How would it make the games more difficult? The programming of the games will not change, simply the frequency at which the calculations are made which may cause a bit of an overdrive in-game but I plan to make a switch to turn it back to OEM anyways and that's why I'm not planning to OC it to anything rediculous... Memory access is a gamble I'm not sure, can't find anything technical on the 3DO to tell me what frequency the ram is or anything like that... I only know the memory sizes 2MB DRAM, 1MB VRAM (VRAM is dual ported), 32Kb SRAM, 1MB Rom. The Bus is 50MB/sec.
The other questionable issue I can't find any info on the 3DO to know is for refresh rates... OCing the ARM60 won't affect that I'm sure, but the co-processors are video processors I have no idea if they have a set refresh rate of 60hz, and my LCD TV isn't one of the new 120hz models, it's a 60hz. I suppose if I build switches for all the OC's, I can try this all out and if worst comes to worst and something get's damaged like a ram chip. All it cost me is an old 3DO, right? Unless you can tell me right now it's not gonna work? Which would explain why I can't find info from anyone having ever done it on this system before 'cause this thing really needed a performance boost, slow frame-skippy junk-o-ware... I have a feeling the Dev kits were higher end.
