I imaged an MSX cassette labelled `Othello` containing Bitgame's tape conversion of Sony's MSX ROM release of Computer Othello. The ROM image stored on the cassette differs slightly from the Sony ROM cartridge I dumped previously, but all the differences appear to be erasure of the original author and publisher names. The case spine is marked with `CST 059` which may be a product code. The tape pressure pad was detached due to adhesive failure but it still loaded fine. Side A contains the software, and side B is blank with nothing recorded. This tape contains a BASIC first-stage loader wrapped in a machine-code loader, followed by the 16KB modified ROM image of Computer Othello and a small machine-code helper routine (probably a copier to copy that part to start at address 0x4000). I did not find this tape release of the software catalogue by others. The two tape files are named `OTHELL` and `oth` and are both of the BLOAD binary type.

This tape will not work on many non-Argentine MSX models because the 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.

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.
