Bubble Bobble featuring Rainbow Islands
Windows (published by Xplosiv)
Runs an emulator (Z80.DLL), SecuROM protected.
DOS (version this page is about)
Seems to be a direct port of the PSX version, which does not emulate a Z80.
Some but not all files are compressed using Rob Northern Compression. When decompressed, they will be either of PCX Format or LBM Format, for the latter appearing to be taken from the PSX version with chunks such as PSX, CL00 (CLUT, 16-bit colors), TP00 (texture page, raw image), BX00 (unknown).
