Just wanted to post here publicly about the RS-97 handheld. It uses the same shell as the Revo K101 GBA clone console, but it is NOT a Revo K101! Here's a few nice features:
OpenDingux compatibility
nice bright high resolution screen (320x480)
plenty of buttons for emulators
rca tv out (can be spotty with some apps)
headphone jack with stereo output
charging via mini usb
internal and external SD micro SD card support (up to 32gb)
emulators for basically every console (I played through warioware GBA and had no issues)
you can actually buy them and they're only $50 (biggest feature IMO)
Initially the distributed lgpt dingoo binary did not work due to the RS-97 having twice the vertical resolution as the dingoo, so the screen was super squished. I'm happy to report I've worked with some of the awesome RS-97 community to add LGPT support. As of now as far as I can tell everything works (the 10k demo song plays totally fine).
The one disappointment is that we have not been able to get MIDI working. The RS-97 includes the GBA link port from the K101, but it's not functional. I modded my console to re-wire a UART to the link port and then connected a USB to Serial adapter on the other end. I can succsessfully get serial debug data out of the console, but as soon as you activate the serial port in LGPT it dies. I can't imagine that it's going to be a ton of work to get it working fully, but it will require a hardware mod and a special gba-midi cable or adapter (pretty trivial to make).
I have purchased two from eBay and they are different hardware revisions but both work fine with LGPT.
Here's some useful links:
