Jeff Parsons took the visual ROM dump I made from the siliconpr0n TMC1501 dieshot and (after I found 2 bad bits and he found 2 bad bits) wrote an emulator for the TI-57 calculator: https://www.pcjs.org/blog/2017/11/05/

While we were emailing back and forth, I noticed that the chip package shown at Datamath.org has the label TMC1501D-NL, compared to TMC1501NL on his calculator and mine. I'm wondering if that D indicates a ROM revision.

I picked up a Jeppesen Sanderson avstar Flight Calculator made by TI, but it has a TP0320.

Here's a very recent game that would be interesting to see if it could be emulated:
http://superimpulse.com/our-brands/tiny-arcade-2/

These are really tiny versions of arcade games, that use full-color pixel LCD screens. There's only four, and they all use the same board and ROM (there's jumpers on the board that determine the game played).
Someone has managed to dump the ROM already, as it's a separate chip on the circuit board, but we aren't sure what the processor is (under a glob)...

Here's a .zip file containing the ROM and a picture of the board and datasheet for the EEPROM:
www.handheldmuseum.com/Z_Imgs/MESS/TinyArcade.zip

Any thoughts as to what the processor might be? We have a spare board (the one he dumped the ROM from) if you want to attempt to de-glob it...

The code doesn't look like any processor I know, but the sounds / music are all WAV files with all the ID tags filled out. One of them is "Galaxian 1979 Namco Mame Retro Arcade Games", meaning they apparently sampled MAME.

They are actually YouTube videos. you can find the exact title of each of them on YouTube, usually just a play through of the game.

I'd swear the intermissions on Pac-Man look like compressed video too, like they just used low res MPGs instead of coding them...
