R-Type 2 by Irem (1989)

A big thank you goes out to Barric, Diss, Norfolk, England who donated their
expertise by removing the mask ROMS soldered to the board so that I could read
them.

L0->L1, M0->M1 were 27C1001 EPROMS
SP was a 27C512 EPROM 
VO file was a 27C1001 EPROM
G00->G31 files were NEC 23C1000AC mask ROMS (in a 28-pin package, split U/L)
N0->N3 files were NEC 23C1000AC mask ROMS (in a 28-pin package, split U/L)
