Hi. I got a cheap Saturn Game Buster cart today and it has Action Replay 1.5b firmware on it. Is it possible to flash a pseudo firmware to this to allow loading backups or at least find English firmware for it as it's in German? Thanks.
I couldn't get pseudo to work on it but I'll try it again tomorrow. I got a firmware to work labelled ARS-194C I think it was? It won't play backups but it's in English now. I was probably just doing something wrong but I was using the disc swap method.
Just want to report back that I got it to work with Pseudo Saturn Kai Lite - V6.074 EDIT: Is it complicated to modify the Saturn with a second oscillator to achieve 59.9Hz instead of 59.3Hz? It seems to have frameskip on some displays due to the odd timing while some displays are fine with it.
It's definitely possible, i went the route of installing a switchable oscillator. https://nfggames.com/forum2/index.php?topic=5744.0 Pictures of my (not so pretty) install https://imgur.com/a/Ohpnd Edit: More Saturn specific details here if you open the spoiler on point 2 https://circuit-board.de/forum/inde...requency-Oscillator/?postID=464215#post464215 I essentially just removed the original crystal and connected my oscillator instead, the switch input of the oscillator is connected to pin79 of VDP2 and a switch so i can change the Saturns video mode and the oscillator frequency at once. It's not exactly easy but definitely possible.
I literally have mine done like that except without the oscillator. I didn't lift pin 79 though, I cut a trace instead and just soldered a wire to a point on the board. I switch that between 5v and GND for PAL and NTSC. My mod isn't that pretty at all but it works so I'm ok with it, but I really would like the oscillator mod so I can get the correct framerate. I'd rather not play slower games and I'm worried that even if I do buy a new TV that it will have frameskip issues with the Saturn despite being a really expensive TV.
On a lot of PAL boards you can indeed just cut a trace and install a switch that way, i didn't want to dick around finding the right points for mine so i just lifted the pin instead. Your method is arguably superior since you can easily use the standard oscillator frequencies (SAT_4xNTSC_4xPAL.hex) whereas i needed the wonky corrected version. You could also put two oscillators on a piece of strip board and switch the output of that as long as you can get your hands on the right frequencies.
Since I already have the trace cut and a switch hooked up, is it just a case of removing the oscillator, attaching it to a strip board or something like you said, getting the correct frequency oscillator for NTSC and also putting that on the strip board, getting a double pole double throw switch and wiring one pole up to switch the oscillators and the other to that point that leads to pin 79 (where I cut the trace) for switching between 5v and GND for PAL/NTSC?
