What this specific tape needs is "APSS fast-forward" support, which is basically "scan forward the tape input until you find silence for 4 seconds", as an analog mechanism to find a track. Kludging it to around 4:00 (which is where silent can be first heard for 4 seconds) makes the tape version to boot although a tad too slow, could be due of the kludge or not. Anyway, I guess this one needs mods to cassette device or a subclass of it, because APSS is a Sharp standard. And deassigning since I'm not that confident with the silent part & with the TAP format itself.
