Re: Stunt Race FX Issues

srg320 made the Super FX implementation from scratch. It has been reported that the Star Fox ending runs at the correct speed unlike the SD2SNES.

Stunt Race FX enables 21Mhz mode and high speed multiplier so it is probably something related to the higher speed.

Re: Super Game Boy SNES core with MSU

Maybe it is something like that but usually reloading the bios does not work and the core has to be restarted so it is unlikely that just the bios is decaying.

Re: Super Game Boy SNES core with MSU

Such an outstanding work to fit this and make it work, thank you so much for implementing it. Removing the cartridge special chips freed up a lot of resources. The memory for the GBC part could also be removed like WRAM(24KB) and VRAM(8KB). I used Sorgelig's SDRAM controller from the NES core which has different channels. So SNES and GB both use s...

Super Game Boy SNES core with MSU

Finally convinced myself to try to combine the SNES and Gameboy cores so all Super Game Boy functions could work. Well here it is. It is the SNES core modified to only support the Super Game Boy because it can't fit otherwise. Even Gameboy MSU works since the SNES MSU stuff is still used. There are 3 speed choices. SGB1, SGB2 and SNES. The SGB2 opt...

Positioning and shake effects will also work better. Sync 480i for HDMI: This will keep the line count/refresh rate the same in 480i and 240p to prevent sync loss. If you enable th...

Re: Can't understand how to get pixel perfect resolution on my Philips CM8833 CRT

It is not so odd. This core forces cropping to 216p when the output resolution is 1920x1080. This cropping also affects the analog output. (Analog being affected by 216p happens on all cores. Something which should be improved)

If you enable Direct video then the resolution is changed so cropping is disabled.

I am looking forward to your MiSTer core source. I am assuming you will simply output a 4x color clock to the Vsync output?

Re: Adjustable Composite Converter?

With my adapter is possible to send directly the color carrier clock, through vsync pin. But there is no support for that in the cores. Yup, exactly, that's what I meant when I said "I get the feeling it will be a long time, if ever, before we see cores that send the correct frequency to adapters like Antonio's that support the signal." ...

Re: Cannot see JAMMA controls through JAMMAsd or IPAC

Well you must be doing something wrong then. jamma_vid/pid is basically used for translating a keyboard to 2 joypads.

Most cores don't support keyboard for controls and as you noticed the input tester also does not. So it is needed to use jamma_vid/pid.

Re: Lag tester core - diagnosing variable lag?

You should probably try pin 1 of the P7 connector on the IO board. The instructions say pin 2 of the Arduino should be connected to the User IO TX (D+) line. On the P7 connector TX is pin 2 but D+ on the USERIO(USB) connector is connected to pin 1 of the P7 connector so the instructions don't make sense. I can't find the source for the NES lag test...

Re: Lag tester core - diagnosing variable lag?

Definitely something wrong if you need to load a ROM. Obviously it wouldn't make sense to rely on a ROM polling the controller for this

Maybe you connected the wire to the wrong USERIO pin or maybe you have SNAC enabled which is interfering.

Re: Non uniform color of gradient ramp with analog output

With the 6 bit limitation of the IO board you might see uneven brightness but since grey color means 3 equal R,G,B signals there shouldn't be any tint. Unless you are using YPbPr.

Check the grey ramp in the SNES core. It has a more linear color output than the Genesis.

You should also make sure you are not using Gamma correction.

You need to set System to Auto or Gameboy. Custom palettes don't work in Gameboy Color mode because then the Gameboy Color applies its own colors to background and sprites.
