For instance, there’s a Palm emulator called Mu in the super core that built, but I haven’t tried yet. That said, I’m always curious to see unusual things being emulated. But that seems like more of a bonus goal, since I’m guessing most of those cores cover systems that will already be working well enough in a different core, or they are more esoteric systems that few people (including myself) will care about. I’d like to either build those cores separately from that repo, or from a standalone repo (if one exists). Also, there’s a ton of stuff included in the super repo that never actually gets built either because it tries and fails, or it isn’t even included in the build process. I did try the Jaguar core from super and it was terribly slow running Tempest 2000 (which is one of the few games I might want to run on it anyway!) My long term plan is to try building from the standalone core repos in cases where the super version performs poorly, just to see if there’s an improvement. I’m thinking for any that work (well) I’ll post them to my repo here. I haven’t tested many of the cores from the libretro super build yet. The VICE libretro core is standalone and not from “super” (which either wasn’t included or didn’t build), but this one works fine. Stella works great, and I’m not sure if the standalone version is any different performance-wise to the libretto core, though the standalone likely has more tweakable options. I’m not sure if that’s a problem with PPSSPP Linux builds or if it’s something specific to the DevTerm and perhaps I should have used different build options. Flycast works great and seems like it has the potential for many playable games (though 3D stuff has noticeable slowdowns, which leads me to believe my build doesn’t use proper hardware acceleration.) PPSSPP runs at a good speed but there are graphical rendering glitches that make some games unplayable or cause issues. Dolphin is more of a novelty and while it works I’ve not found anything running at playable speed. Both MAME builds are quite functional and work great depending on how demanding the game might be. Look at the console-specific page in the sidebar of this wiki and note where the system's configuration file.įor example, the GBA config file is /opt/retropie/configs/gba/retroarch.cfg so any changes made in there will apply only to GBA games, not to other systems.At some point I will post threads for each of them, but I want to do more testing first. (1080 - 480) / 2 = 300 is how far to offset vertically. (1920 - 720) / 2 = 600 is how far to offset horizontally. To do this, we take the (original resolution - console resolution) / 2.įollowing our example of a 1920x1080 screen showing a 720x480 GBA image, do the following: Now we've determined our actual display resolution, and the resolution we want the game shown at, we need to centre the image on screen. An image of this size fits within a 1920x1080 display, is smaller than the full 1920x1080 display, and is still in the same aspect ratio so the game won't look stretched. Multiplying by fractions (eg: 2.66, 3.75, 4.4) may end up with strange ugly pixel effects, especially if using shaders which apply scanlines or similar effects.įor example, the GBA resolution was 240x160 so we'll multiply those up by 3 to land on 720x480. It is best to multiply by a whole number (eg: 2, 3, 4) so the original pixels get sized up consistently. Take the original console resolution and multiply both numbers by the same amount to get a larger gameplay resolution which is still in the same aspect ratio and fits within your actual display resolution. Later home consoles (SNES, Master System, Mega Drive) often had multiple display resolutions and are not covered by this article. Determine Console Resolutionįind the original resolution of the console by looking it up somewhere like Wikipedia. You may wish to refer to the Wikipedia Display resolution page. If your TV or monitor displays at another resolution, find that out and keep it in mind. If your TV is displaying at 1080p, the resolution is 1920x1080. ![]() This tutorial covers making the display of a RetroArch libretro emulator smaller and centred on the screen. This is especially true of handhelds like Game Boy and Game Boy Advance where the original resolution was so low that blowing these up to 1080p results in HUGE pixels. Some people like to have their gameplay on a smaller area in the middle of the screen, rather than blown up to the full display resolution of their TV.
