Jetson TK1 Thread [Notes / Issues]

RetroArch Linux devices
#1

Greetings, I just discovered Retro Arch and all the wonderful modules it provides, and it was exactly what I wanted my Jetson TK1 to become in the first place.

I thought I’d start a thread to document problems, solutions, issues, and general concerns regarding Retro Arch and Jetson TK1 users.

I’ll be posting my notes and issues here soon, and if anyone needs me to test anything on JetsonTK1 hardware, feel free to PM me if it’s not in the Testing PPA.

Everything runs super fast, games, menus, everything:

Go to Settings > General Options > Limit Maximum Run Speed > ON

The sound is SUPER choppy and distorted:

Go to Settings > Audio Options> Audio Latency > 256 This isn’t a 100% fix, but it makes the sound tolerable in most games.

4DO does not accept the BIN/CUE format:

Picodrive ran my Sega CD game one time, but now won’t anymore:

Genesis Plus GX/Neopop/[Emulator here] is only showing part of my game’s screen:

Double click the top of the window bar to make it full screen.

DeSmuME doesn’t work:

Don’t worry, it’s still in testing. Log file here: https://dl.dropboxusercontent.com/u/67355064/nds_log.txt Update: Reset config files, it works now.

So I rebuilt the emulator to include the “#extension GL_EXT_frag_depth : enable” but now the emulator crashes without any errors… https://dl.dropboxusercontent.com/u/67355064/log_mupen64plus.txt
