I imaged a loose MSX cassette labelled `Wonderboy` containing Boggia Microinformática's tape conversion of Hudson Soft's `高橋名人の冒険島` (Takahashi Meijin no Bouken Jima, i.e. Master Takahashi's Adventure Island) MSX Bee Card ROM release of Sega and Escape/Westone's Wonder Boy arcade game. The ROM image stored on the cassette is identical to the version I previously dumped from the Bee Card. Side A contains the software, and side B is blank with nothing recorded. This tape contains a BASIC first-stage loader, followed by a machine code loader, followed by the two 16KB halves of the ROM image 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 named tape files are both named `bµ msx`.

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.
