Sean, can you see if you can locate this, I'd be very surprised if it wasn't another 6502 one like Space Invaders.

There's a sprite ripper here that's fairly arbitrary, written by Marc Lafontaine:

BIOS-D however recommends THIS one: http://www.mameworld.info/ubbthreads/showthreaded.php?Number=372953

I found Incog's Tetris and deglobbed the MCU- it is the same die as on Space Invaders: ELAN EU3A05. There is another glob that has TSOP48 pads that looks like the same pinout as the ROM on SI, so I'll wire it up and dump it. There is no 3rd glob or chip.

I wonder if the 3rd glob is to handle the pixel layer or sprites some of the games in the Space Invaders one need, basically just a bunch of RAM, tetris looks like it's all tile based so wouldn't need it.

Thanks! I just downloaded them both and I'll play with them tonight.

could this be it? http://www.emc.com.tw/eng/8bit_prod_dsc.asp?gid=&tid=000002&tt=8bit_fadc_ds&nn=Flash+ADC+Type+with+EEPROM+(66X+series)

That's not a 6502, it's some custom architecture from what I can tell.

FWIW, Wikipedia says EMC EM78 family are PIC clones.

Here's the Tetris ROM dump: www.seanriddle.com/tetrisrom.bin I see a lot of tiles, background graphics, "Battle Garbage", and RAM check/ROM check diagnostics.

Here's a pic of the dumping rig: www.seanriddle.com/spaghetti.jpg Tetris board is on the right with the CPU deglobbed and 33 wires soldered between the TSOP48 pads and a proto board with 48 header pins. PIC18F46K22 powered by 2xAA batteries drives the address lines while Logic 16 captures the data lines and a flag output from the PIC to make it easier to separate the bytes.

I can confirm Tetris is the same hardware, same ports being used etc. for everything.

Doesn't boot yet, but that's not really surprising considering that the driver is a bit of a hack for the Space Invaders :-)

I'm guessing the CPU used by Radica is more or less the 6502 equivalent of what the Kawasaki KL5C80A12 is to the Z80: a high-performance core providing just the standard instruction set plus an assortment of on-chip peripherals, here almost certainly including a MMU as well as an interrupt controller.
