I tested this a while back. The Vita is just not fast enough for MT-32 emulation. The sound is extremely choppy and the games run very slow when MT-32 is enabled. That’s why I disabled it.

The Nintendo Switch can run MT-32 Emulation just fine.

It should work, because I am already using the exact same toolchain as the buildbot (I updated the buildbot toolchain at some point not too long ago). But we'll see.

I made a few tests on Vita, using latest ScummVM github code. It is perfectly fine for now to just disable lastexpress and keep all other unstable engines. Lastexpress is one of the largest unstable engines. Disabling it prevents the crash on startup that was reported here. Note another large unstab...

Yes, -Os optimization removed the need for the hack, but startrek might have pushed it over the edge again.

I think the star trek engine is already playable. Maybe other, unplayable engines should be disabled instead?

The PSP port has this ingenious "1st person RPG control mode", detailed here: http://wiki.scummvm.org/index.php/PlayStation_Portable It is an alternate mapping for EOTB and similar games (works great for Xeen, too). It allows strafing with L/R and turning with the dpad. Since we have global game con...

On the Vita, only the keypad keys are mapped to the dpad, not the cursor keys. E.g. dpad left is "keypad 4." This is because most adventure games use the keypad. It also enables better diagonals by mapping R + dpad left to "keypad 7" for diagonal motion.

Please try a clean install: Please rename or delete scumm folder, and install a completely fresh folder with all content from 2.0.0 release zip. Also, please rename or delete scummvm.ini from the root folder of your memory stick. Also you might try the latest improved development version here: https...

"It works for me," so we have to find the problem on your end. Maybe try to rename or delete your scummvm.ini on root of memory stick and do a clean install of scummvm into a new folder. Also make sure you copy over all files when you install, including all plugins in the plugin folder etc. It is no...

This is a working build of ScummVM for the PSP based on 2.1.0git development source from 2017-01-05.

Performance:

ScummVM runs on PSP and PS Vita without slowdown.

Dosbox runs like a slideshow (10 fps?) on those platforms.

A fix for this has now been merged into the official ScummVM code. Thanks to all those involved! Sadly, current development buildbot builds crash when loading any game due to some other, non-related issue. This will be not be fixed until a new Docker-based buildbot is implemented. In the meantime, y...

I remember that Monkey Island had a big black bar at the bottom when I played it back in the day on the Amiga, e.g. it did not run in 4:3, but in some aspect ratio closer to 16/10. To check if Monkey Island 1 should be played with aspect correction, I took two screenshots of it running in ScummVM. T...

With help from wjp and snover I pushed a fix to the Phantasmagoria bug on Vita. So that game should also work fine now as of today's buildbot version.

Hi, As everyone probably knows, the PSP ScummVM port has incorrect 4x3 aspect radio. That is why I have recompiled my own version of ScummVM that removes this inconvenience. Below are the screenshots of the original port of the PSP port (upper image) and my version (lower image). https://image.ibb....

Does anyone know how to run SCI32 games (like Larry 7) on Vita with latest daily builds? Game is detected but after launching only black screen appear forever. Using latest daily built from Nov. 30 2017 from buildbot, I tested three SCI32 games on Vita. They took a while to load. - Leisure Suit Lar...
