StillMeet6836 from reddit shared some info about his console.
I have one of these. Few points to note:
- I opened it up and still can't figure out what chip it's running.
- There's no retroarch, but pressing select+Y with a rom highlighted gives you the option to load the game using a different core.
- the battery is located behind the screen, making this top heavy. The battery is also soldered to the motherboard rather than using a detachable clip.
-The OS on this appears to be CUBEGM - The same os used on things like the M15 Gamestick HDMI dongle
"Dom_Bomb" adds:
-I have one of these. I looked at what rom files this had on it. It contains .iso and .img files for ps1 games.
-When I added .iso roms they would not load. I added .bin and .cue files and they loaded fine. -Unlike other similar handhelds it does not seem to support .chd files.
-In order to save space and after doing some research, converting to .pbp files saves space. Most worked at full compression using psx2psp. Those that didnt i used level 3 and that seemed to fix it. -MGS in any form will not play as it hangs on a black screen.
-As there is no retroarch there is no disc swap feature.
-Seems you cannot add other cores. Ive tried according to similar R36SX guides to no avail. You can change core as StillMeet6836 states but there is only "default" for PS emulation.
-The R36SX Art scraper and R36SX CSV Generator work with the GB350 and you will need to use the CSV generator if you wish to add roms before reinserting your memory card into the device.
-In addition i had a very hard time removing the sd card, and reinserting. If you have a similar problem i found whilst tinkering (adding games/media etc) just to hold it in place. Not the best solution i know.
