Here are the dumps from a (original???) Rolling Crush (version 1.07.E 1999/02/11) PCB.Game seems to be a rip-off
of Puzz Loop from Mitchell,  infact there is a piece of tape on the solder side which says 'P. LOOP' and a sticker with 02/1999 date.Manifacturer is TRUST.
All EPROMS four 27C2000 (program code), one 27C4000 (6295 samples), 
one MASK 27C512(GFX), two 27C160(GFX) and two 27C010 (GFX) are not labeled.
Main CPU is a 68EC020FG16 in QFP package
There are also a Atmel AT89C52 MCU (dumped as well since it seems not secured) and two Actel A40MX04 FPGAs as well as a lot of PLDs (three GAL22V10B and nine PALCE20V8H), don't know 
if secured.
See measurement.txt for clock/video measurements.
Thanks to 'Osso' for buying and sending/donating me this PCB so, please, credits must go also to him  (add also his nick along with the dumper 'caius')
