[REQUEST] SNES unlimited sprite and overclock enabled

Open Jord4n opened this issue 7 years ago • 11 comments

Think this is a feature in Snes9x? Does not seem to be enabled in Snes9x 2010

During game, press START+SELECT to get to RetroArch menu and see if you can activate it there.

Problem is: there's only 10Mhz, then 40, 60, 80, 100 Mhz... for Starfox (PAL) 15 or 20 would be good. Well, I tried boost-fx 2 on Starfox (ntsc) - I assume that is 20Mhz, and even that is a bit too fast.

There is only an option for the SFX chip. Not for games in general. There is also no unlimited sprite option.

@K4Z1 --boost-fx multiplies the speed of the Super FX chip in any games that use it. You seem to want to overclock the main CPU.

@gingerbeardman I'm pretty sure my PAL Star Fox (Starwing) which I use with retroarch runs at 1/2 of the speed of the overclocked (-boost-fx 2) original Star Fox.

@K4Z1 let me see your scientific proof ;)

I set the -boost-fx to 1.5 and I think it actually worked (15Mhz?), looks smoother than the original and does not look like hyper-turbo-mode... It still doesn't affect PAL games in retroarch. Will try to find the config where it says 40Mhz and change that to 15 or 20Mhz (because PAL is slower anyway) if it works lol.

boost-fx is for the in-built emulator only.

Let us know if you find the RetroArch setting.

Hi sorry everyone. Yes I was talking about overclocking the main CPU to eliminate some slowdown in SNES games. Also to unrestrict the sprite limitations (to reduce flicker) like some other cores do. Looks like this wasn't possible on the original Snes9x. I don't think this has been done before. Wondering why not, as cores for other systems have this feature...?

@Jord4n you cab get these other cores for RetroArch on SNES/NES mini. I'm not familiar enough with the various SNES cores but you might have luck. Let us know!

"Let us know if you find the RetroArch setting."

I can't find any setting for that, it's somewhere deep in the codes of the core (lol), way beyond my skills, I'm barely able to switch my PC on and off, so...

I don't even know who makes these snes9x cores... Anyone knows? I wanna ask them to add a 18MHz boost, or custom number... 18MHz should be ~1.8x boost = PAL 50fps x 1.8 = 90fps. Just like NTSC 60fps x 1.5 = 90fps ...which feels good on Star Fox.

This video has 20MHz, a bit too fast still, but better than 40MHz: https://www.youtube.com/watch?v=3gVg8vDhfQk
