Here is a headered copy of the long-awaited Play Vision 95-in-1, featuring Advance Bright Limited versions of Inventor hacks. The Play Vision ROM is modified from the better-known "Vs. Maxx Maxxplay" plug & play, featuring the same otherwise-uncommon hacks as that system (e.g. the Pac-Man hack "Egg It").
While I plan on doing a full game extraction of the 95-in-1 eventually (as virtually every game on it was previously undumped), I wanted to share this finding beforehand. To represent the Track & Field games, the 95-in-1 uses a modified version of Nice Code's "Olympic" game; which is separated into eight separate "games" in the menu (despite reading off of one ROM file internally). However, a separate, unused hack of Track & Field is present in the code; this hack has never surfaced on another plug & play, and I suspect that it was solely designed for the 95-in-1 before being scrapped.
Similarly to the Nice Code games on the final console, the Track & Field hack is intended to be split into eight separate menu entries, each with their own "title screen". As such, the unaltered ROM solely loads one round of the 100-Meter Dash event (featuring a title screen reading "Whiz"), and displays the high-score as corrupted tiles (not that you'd ever reach it anyway...). As a partial solution to this, I converted the game back into a generic multicart menu; allowing its eight events to be selected with their altered title screens. An ideal solution would be to patch eight individual ROMs to load the events, though I am unsure how to do this myself.
As an additional note, the Track & Field hack's PRG code is duplicated across the CHR chip...22 times, for some reason. I feel like this may be a new low in lack of coding care with these things, but it's a tough call. In terms of further unused contents, the only thing that I see is an unhacked copy of 4 Nin Uchi Mahjong, for whatever reason; I presume there aren't any other secret hacks buried inside.
