Re: Gryzor - interesting bootleg
I didn't know cyee was a Kaiser employee. But your dumper may have transcoded $8010 - $8017 to $b000 - $E003zxbdragon wrote: ↑Wed Nov 25, 2020 7:27 amwhat?cyee is kaiser staff....aquasnake wrote: ↑Tue Nov 24, 2020 6:39 amthis cart can't be Kaiser's conversion.

If so,
If using a dumper such as copynes, you may get the ROM that has been decoded rather than that has the original data order

This is just ordinary VRC II. Interestngly, your PCB looks like almost identical copy of original one, just without those "tracks to nowhere": (used for plating)
