rg351p-ppsspp-settings VS arkos

Here is a list of games with level of playability. Your game is not listed but it might give you some indication on other games and tweaking settings. However this list says the first one runs well on rg351 which is a weaker device so I'd would tend to think you're clear :)

An alternative is to download game setting files from https://github.com/jserodio/rg351p-ppsspp-settings/ You would put the .ini files in psp/ppsspp/PSP/SYSTEM/ on the second SD card (you may want to make a backup of that folder first). This doesn't cover every game but, for those it does, it will provide the best available performance. This is what we do.

Lately I've been using mine for PSP games and got quite a few games to run either at full speed or with the framerate locked at 30FPS, here's a list of a few compatible games: https://github.com/jserodio/rg351p-ppsspp-settings/wiki

there's a github page that has a decent compatibility list for psp games that run on the 351 series and some of the setting you'll want to use for certain games

For PSP emulation, I recommend using the PPSSPP-GO emulator, and utilizing the per-game configuration files from https://github.com/jserodio/rg351p-ppsspp-settings/

Coming from a MM+ and having a tough time getting my RGB30 set up to fill the screen across various emulators. I've looked at this and this and this, among many other great resources.

ArkOS is very similar to JELOS, and can do this via Quick Mode. If you also go into Start > Advanced Settings and switch On the Switch Power Button Tap to Off setting, it's pretty handy. No Quick Mode -like function in JELOS... yet.

edit: if you're trying to install arkos, instructions for macos are included: https://github.com/christianhaitian/arkos/wiki
