Naomi RAM and SRAM Questions
Posted: Wed May 04, 2011 10:01 pm
Hi again.
Picked up my two Naomi games from the mail today and while I've had some fun with them afterwards, there's a couple of questions and concerns that I have on my mind.
Firstly, I set my Naomi to Free Play since I don't have a coin harness nor do I plan on using one yet, but whenever I insert a cartridge or swap my two games around, the SRAM defaults back to 1 credit = 1 coin mode. It's rather irritating to keep going into the test menu to change it. Anything I should be doing? The CR2032 batt is working fine BTW.
Secondly, when I first took my Naomi out again having left it unplugged and unused for a while, I put a cartridge in and it showed serious graphical glitches and slowdowns even on the BIOS. I thought the cart was drawing a little to much power so I removed it, turned my Naomi on yet it still did the same errors. Tried the other cart wth the same problems. I tried cleaning the IPL's legs and making sure that all wiring was connected. I cleaned any dust out of the ROM's sockets and the IPL's socket still nothing. Then once it wouldn't even boot. I left it for a while and later I plugged in Virtua Tennis, and it booted fine with no errors at all, until the game played, which there was some pixels and errors. Left it for a while and since then it's had no problems at all.
I'm seriously worried there's a fault on my board since I know they're not cheap to fix. I have no means of testing the voltages, but I'd assume a PC powersupply only sends the current out when voltages are stable, but then again I'm a n00b with that. Before Andy said that the RAM chips might be going, but the test says they're fine...
Thirdly, does EPR-E-21576 work with the GD-ROM? If so, network? *shot*
