I imaged an MSX cassette containing Microbyte's tape conversion of Prosoft's Korean ROM release of the Namcot Japanese MSX ROM release of Namco's Galaga. Microbyte is identified inside the BASIC first-stage loader as well as on the packaging. Prosoft is identified in Hangul with a stylized encircled 프로소프트 ("Prosoft") logo on the game title screen. Side A contains the software, and side B is blank with nothing recorded. This tape contains a BASIC first-stage loader, followed by the game with an attached machine-code helper. Other than the 16-byte ROM header being removed and replaced by other code, the copy of Galaga's ROM image stored on this tape is only one byte different to the Prosoft ROM release - and exactly the same as the one I found on a different Argentine release from Bitgame, so I now trust the decoding for both tapes. I did not find this tape release of the software catalogued by others.

This tape will not work on many non-Argentine MSX models because the game loader makes an assumption that the MSX has 64KB of RAM in primary slot 1 which it has selected as its primary memory, which was the case for commonly available MSX models in Argentina (e.g. Talent DPC-200 and TPC-310) but was relatively uncommon elsewhere - though the Spectravideo SVI-738 also works this way and can run the game. It can be made to work in other MSX models with a free slot 1 by inserting a large enough memory (64K or larger) there that will be selected by the BIOS as the primary memory. After the ROM image is loaded into RAM - including copying to its final address - the game is launched directly without rebooting.

CAS image fingerprint for the software found on Side A:

Raw 24-bit stereo 44100 Hz FLAC audio was imaged using a Nakamichi BX-125 tape deck and a Steinberg UR22mkII USB ADC with Audacity under Win11 and is intended to be archival, CAS/ROM is for emulator use, and WAV is regenerated from CAS for the benefit of an actual MSX. Short filenames and long ones contain the same data.
