Re: N64: To PAL or not to PAL?

You can also do that native on the core. Just set system type to NTSC with a PAL game and you get 60hz.
But if the game uses more height than NTSC allows or cannot handle the higher speed, it might not work.

if the logo comes up and hangs afterwards, you didn't patch it right. Everything else is likely set up correct.

Re: N64: To PAL or not to PAL?

Some games unfortunatly use the the NTSC resolution and scale them in the VI for PAL
Examples are WaveRace and Mario Party. It makes these games much blurrier with PAL.

I will play the PAL version regardless :)

It is a feature to make the screen black in case of resolution switches for 3 frames, because otherwise you would might see garbage on the screen.

I'm having trouble with the controller. most of the time I can move everything in the menu but in the game the buttons work but The analog or digital directional buttons only work in the menu and not in the game

Be sure to map the controller and analog axis in the menu core(that comes up after turning on mister), before you select the N64 core.

Re: Converting EEP and SRM Saves to .sav

I converted a eep file by just renaming it.

Check the file sizes: if it's 512bytes or 2048bytes, you can just rename because it's the pure data.

Be aware that the core currently only supports EEPROM saves, no SRAM or Flash. So if you have bigger save files those are likely not EEPROM and you need to wait for the core to support them.

Re: FPGA Sega Dreamcast?

Highly FPGA optimized soft CPUs (e.g. NIOS2 from Altera themselves) run up to about 170Mhz on the DE10-Nano. That is the absolute maximum you can expect. Given that other original CPUs are not highly optimized for FPGAs, you can expect lower clock rate. On newer FPGA architectures this is not a big issue anymore. Xilinx Ultrascale+ can run their hi...

Re: PSX Core Audio and Video stutters twice every 3-4 seconds - All Games

Great that you found the reason.

When the linux is busy, you usually don't notice it at all as most cores run in FPGA only.
It's usually only the consoles with CD or computer cores with HDD access.

Re: PSX Core Audio and Video stutters twice every 3-4 seconds - All Games

Stuttering means the game pauses, because the linux part(mister main) is not fast enough to provide CD data. Possible reasons: something is running on your mister main in background. Some script, controller constantly connecting new, network transfer, ... your storage is too slow. This can happen with USB HDD, but typically not that often and i nev...

Re: Atari Lynx's Gauntlet Video Orientation and 240p Mode Issue

Gauntlet is vertical and 240p mode cannot do vertical.

Normal res is 160x102 pixel, vertical is 102x160 and 240p mode is 320x204 pixel centered in the middle with every pixel doubled

So if you play vertical games, i fear you have to modify the settings or use some mra file for those titles.

Unscaled resolution for GBA2P is 480x160(hor) or 240x320(vert) or 240x160(single screen) The screenshots don't work properly as the GBA2P is using direct framebuffer mode. But if you open up the OSD and go left where the volume control is, you also see the scaled and unscaled resolutions. I can't answer why the scaling doesn't work as expected, pro...

Re: Gran Turismo replays often desync

Yes, unfortunatly this is still in. The issue with replays is that they must hit the exact same speed or higher when playing back. As the core aims for 100% original CPU speed, there is no buffer and some slight inaccuracies let it drop below 100% and result in a missed input for the replay, which can mess up everything. There are 2 solution: 100% ...

Hard to justify a swap option for this special setup, but you can easily swap the analog stick direction in the source code if you really want to.

Pokemon red? This is the GBA subforum, so i'm not sure if you either talk about Fire Red or about the gameboy core.

Are you sure you have autosave on and opened the OSD after saving ingame before turning the mister off?
