Re: SNES core

A few more attempts later, I believe we have stable overclocking on SNES!

Here is the new build:
https://ufile.io/hlvs9i2a

I have sent a pull request to sorg. This build fixes the sound issues present in Super Adventure Island by disabling turbo when NMI is disabled. Enjoy.

Re: SNES core

I decided to give fixing the turbo mode for SNES another crack and I believe I've almost got it. I could only test the roms I can rip from my collection, but here is a list of the bugs it fixes: Super Ghouls And Ghosts - No more graphical glitches on waves or tower Legend of Zelda - Buttons are corr...

Re: Would MiSTer ever be able to run a Neo Geo core?

Furrtek, Sorge, GreyRogue and Rysha,

Amazing work on the Neo Geo core and supporting hardware/software. I cannot wait for my 128mb sdram module, playing Garou, SS5SP, and all the metal slugs is an absolute joy. Thank you for giving the Neo Geo new life, and prolonging it's legacy.

Re: Would MiSTer ever be able to run a Neo Geo core?

@greyrogue

I'm a little late, just tried the new changes, pcm channels sound near perfect on everything I've tested. Beautiful work. FM still pops on some sounds, kof95 song 722, bass line pops.

Re: Would MiSTer ever be able to run a Neo Geo core?

@greyrogue Just tried your changes from earlier merged with the master branch. Huge improvement on note off events, still very minor popping on rapid fire note changes, for example Metal Slug 1, at the end of the round when it rings while adding points. However, this is such a minor pop its likely t...

Re: SNES core

Tried super rtype, turbo removes all lag from the game. It's beautiful. However, it fails to load sounds on occasion. Music will be missing sounds, sound effects will be wrong. Gonna need some fixes.

Re: Genesis Core

Just tried your build of Genesis with turbo, same issue as I had with Sonic 2, music is wrong at 3x and plays at an uneven pace. Road rash at 3x sees an improvement in your build thanks to the vdp fifo changes. Now it needs a software patch, it's input handling seems to have been hardcoded for the l...

Re: SNES core

Turbo mode on snes, beat me to it. Just tested it, works great, Gradius III plays just like the sa1 build up to the bubbles on stage 2. They cause some minor lag, perhaps two turbo modes is in order. Tested Metroid as well, no slowdown at the beginning when the ceiling falls. There is a minor graphi...

Re: Genesis Core

You don't hear it missing it's timing on the song? It's playing it but it keeps missing the beat. This is on the version I made, I'll test your changes later tonight.

Compiling your changes.

Re: Genesis Core

You need both turbo options 1.5 and 3, spinball is ok at both but other games like Sonic aren't happy with 3x.

Re: Genesis Core

Sure, go ahead, was just trying to learn/help.

Btw did you try the build I posted on any of the games that have slowdown?

And out of curiosity, why would you need to disable the vdp fifo?

Re: Genesis Core

I would have sent a pull request by now Sorgelig, however I did some minor refactoring and now Quartus won't produce a usable binary. I even reverted all my changes back to the working code and it produces cores that do nothing. Kind of at a loss here, just nuked my db/output_files/incremental_db fo...

Re: Genesis Core

More testing, now that I can control turbo from the osd I can see the psg is actually working correctly. Only FM sounds are a problem. Interestingly, sonic spinball only uses the FM chip and it sounds fine besides being higher pitched. And apparently road rash is similiar, fm only, audio plays back ...

Re: Genesis Core

Added an osd option for turbo, turning off turbo after loading a game does fix the audio issues. Sorgelig, does the 68k access the FM chip directly as well as the PSG?
