Ensoniq ESQ-1 Hidden Waves question

[lunaquesa]

So I have the standard 3.5 OS installed, and I know you can access the hidden Waves that way by importing SQ-80 patches with waves outside the original ESQ set. You can scroll down through those waves but never back up. If you install Eproms with the Hidden Waves OS, does that let you scroll freely up & down through the hidden Waves, or can you still only scroll down through SQ-80 patches with waves outside the original ESQ range?
Sorry if this question has been answered before, I've been unable to find if it has in all my digging.

It disables decrementing with the up and down buttons (although you can still navigate normally with the data slider; only wave selection is affected), but you can advance up to (I think) wave 255.
It bears mentioning that apart from the first couple of waves beyond the standard rom (which are heavily bandlimited waves mapped in the upper registers of some of the standard ones), the others are not coherent waves themselves, but rather access non-audio parts of the rom and read it out in unpredictable ways. It's awesome for weird, glitchy, polyrhythmic stuff, but stable timbres are pretty elusive.
