I imaged a loose MSX cassette titled `ディジーボール` (Dizzy Ball) containing the Japanese Ponyca release of Pony's Dizzy Ball. Both sides contained the same data. I have not found another description of this version of the game, and this loads in more stages than other versions I have seen described - possibly in order to reduce the MSX minimum Z80 RAM requirement. This game uses a CLOAD+RUN'able first-stage loader and main program with tape filename `BALL` followed by two different BLOAD'able game data binary stages with tape file names `DATA-1` and `DATA-2`. The code `K28X5056` is printed on the cassette's labels on both sides and may be a catalogue number or release identifier of some sort. The code `6A14305` is stamped on the spine of the cassette and may be a media serial number of some kind.

CAS image fingerprint for the software found on both sides:

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 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.
