DEATH Posted September 9, 2019 Share Posted September 9, 2019 Did anyone test the 5-clock clock timing for ROM access with the SD Card? I think if someone manages to run Battlesphere Gold, then it certainly means that the SD card accepts 5 cycles because Battlesphere Gold changes the access speed to 5 from the very beginning.

Tursi Posted September 15, 2019 Share Posted September 15, 2019 No, it doesn't. It doesn't change the access speed nor the bus width from the BIOS setting. Quote Link to comment Share on other sites More sharing options...
Tursi Posted September 15, 2019 Share Posted September 15, 2019 Hmm... digging a bit deeper, seems like I may have misremembered there. Now I need to figure out what the hell I was looking at. Disregard! Quote Link to comment Share on other sites More sharing options...
DEATH Posted September 15, 2019 Author Share Posted September 15, 2019 I quickly looked at the ROM a while ago, and it seems to me that they were changing the ROM speed access. Quote Link to comment Share on other sites More sharing options...
DEATH Posted September 15, 2019 Author Share Posted September 15, 2019 Here -> 82F25E: 0079 0018 00F0 0000 OR.W #$18, MEMCON1 Bit 3&4 of MEMCOM1, value 3 = 5 cycles And this is right after the Joystick test subroutine at the beginning. 1 Quote Link to comment Share on other sites More sharing options...
Tursi Posted September 15, 2019 Share Posted September 15, 2019 Yeah, I was wrong. It turns out what surprised me was that it doesn't change bus width - at the time I just assumed anyone who bothered to set one would set both. I dug into it myself last night too, since posting wrong information on the internet is a dangerous thing! 1 Quote Link to comment Share on other sites More sharing options...
Higgy Posted September 19, 2019 Share Posted September 19, 2019 Battlesphere Gold boots to a red Jag screen. I have not tried the ROM on an emulator to check it is ok though. Quote Link to comment Share on other sites More sharing options...
