I have several of these SD card accepting VT-chip-based famiclones already, I've been trying to document the ones on the market https://museum.12bit.club/SD_card_VT_consoles
This is in line with the others in terms of capability, it can run mapper 0 and 3 and a small number of VTxx .bin files

There are 782 games on the card and "300" built in (with repeats), unfortunately I didn't find anything particularly unusual or undumped in either set so far, both of them mostly consist of regular NES/FC games with some romhacks and Nice Code games mixed in

oh when i said Mapper 0 and 3 two posts ago I meant 0 and 4, as in NROM and MMC3. sorry for spreading misinformation etc etc

as for the hardware itself... you may have noticed it has HDMI output. the video is upscaled with a hq3x filter applied to it. the audio is pretty bad and seemingly missing the native DPCM channel altogether. so I couldn't exactly recommend this as a way to play NES games. It is interesting though!

They also weren't too discerning about what they put on the SD card

@lion if the damage is a ribbon cable and a missing capacitor i can give a shot at repairing it, would have to guess at the capacitor value though

@lion it looks like it might just be a decoupling cap if that's between vcc and ground, nothing should be kept from working without it

@mavica_again i just managed to get it to work by shorting the power switch pins now, idk why it didn't before, but yeah fortunately the cap wasn't critical I guess

@lion lmk if you want this or anything else fixed, you know my address

@mavica_again will do! thanks!!!

@lion oof, forced upscaling filters?

@lion christ I remember this from imockery back in the day
