Well the screen resolution is my main grip with that device. The CPU is a very powerful and should allow to drive way a larger resolution (pyra HD screen would make more sense with that powerful CPU)320x480 resolution is really nice! Makes integer number scaling of the GBA and Lynx resolutions possible.
It looks like someone has ported debian buster to it already. I haven't seen anyone on their board mentioning a working web browser, but I left a comment asking if firefox was working in the thread. I'll let you know if anyone replies.I need a debian / ubuntu device with WIFI and firefox. There is a wifi stick avaible. Is there a firefox version for it? Can you use the analog stick and the buttons for mouse interaction? Just want to receive (not write) emails / discord messages on the go and read some newspaper websites.
My wife would love a dedicated device to replace her long-dead but much-loved (original) Gameboy. That's pretty much it. GBC maybe, but nothing even as advanced as NES/SNES etc.
