Yeah, and for Dragon Ball Z Hyper Dimension, it's a C7 error as well. For information, I tried the japanese game unpatched, with different SA-1 preset IDs (Super Mario RPG, Kirby Ultra Star, Marvelous) (with different sram file size, but I suppose it's not important as I don't even think this game saves anything) and none worked.
If I remember correctly, I think DBZ Hyper Dimension was one of those handful of games that had on-board RAM but not for saves. I can't seem to find a single image of a Hyper Dimension PCB, but I'm going to assume it's the same as the only other SA-1 chip game with RAM but no saves that comes to my mind, Super Bomberman - Panic Bomber W.
That game's PCB is 1L0N3S which denotes:
1 = One ROM chip
L = SA-1 chip
0 = No SRAM chip
N = No decoder chip (for SRAM)
3S = 64kb RAM (used as buffer I believe)
(Nintendo, why not just denote it as 1L3N? But I digress.)
There's actually a stock game on the Classic that also utilizes RAM in this manner, and that's Star Fox. Unfortunately, that game uses a Super FX chip, not SA-1.
I'm hoping otherwise, since I really enjoy this game, but it might possibly be the case that due to the limitations of Canoe and its preset IDs, this game might not ever work on Canoe. I definitely hope I'm wrong though!
