Troubleshooting

• omega-zero.log at the root of the card holds the last session's log, and omega-zero.log.1 the one before. The first lines name the device, panel and canvas omega-zero picked.
• Crashes leave a line each in crash/cores.log on the card. When omega-zero itself goes down, crash/ also keeps what it last said, omega-zero.log, and its memory as it went down, omega-zero.core.gz, for a debugger. omega-zero starts again once the core is written, a few seconds later. A crash within ten minutes of the last keeps the first core, and none is written when it would leave the card less than 512 MB.
• "LAST START FAILED", after the opening, means a game took omega-zero down as it started. The next boot leaves it on the shelf rather than resume it, so one game cannot keep the handheld from starting. Try it on its other core with X (GBA and SNES), or hold A to start it clean, without its resume. If it still goes down, open an issue with crash/omega-zero.log.
• The boot screen is put on the boot partition as omega-zero starts, from System/bootlogo-<width>x<height>.bmp, so it shows from the boot after that. It is only ever replaced with one the size of your device's own, and the original is kept on the boot partition as bootlogo.baseos.bmp.
• Button presses can be traced to input-trace.log by running omega-zero with OMEGA_TRACE_INPUT=1.
• "The Wi-Fi radio did not start", under the networks on Settings > Network, means BaseOS never brought up wlan0. Restart once; baseos-boot.log on the card says what the driver did. The RG35XX 2024 shares its BaseOS image with the Plus but has no radio.
• No ScreenScraper key, said on Settings > Labels, means the build you run was made without the key; official releases carry it. See Building from Source.

Still stuck? Open an issue with omega-zero.log attached.
