GadgetUK, I've finished doing the mods on both my 161 and 138 in 1. I haven't put the optional caps yet as I don't want to add unnecessary components.
So far I've tested some games and all seems good to me (Puzzle Bobble, Matrimelee, Last Blade 2, Nam-1975, Garou, Strikers 1945)
Can you tell me some games that usually have problems on these carts and what to look for in them?
One more thing: Giga Power games for some reason boot two times at start (the green thing at the start happens two times in a row). It really doesn't bother me, but is it normal? If there's a quick/easy way to fix that I'll gladly do that.
Thanks for all your support so far, it's really appreciated!
P.S.: is it me or is the non-hacked version of SVC missing from both those multicarts?
EDIT: ok, I've actually noticed a bug in Puzzle Bobble.
If you hear carefully, you'll find out that the SFX when the ceiling is about to go down (not the one when it actually goes down, the one before that warns you) plays two times in a row, the second one a little bit louder and distorted.
Is it because the Puzzle Bobble rom is corrupted or... ?
EDIT: meanwhile... I discovered there were two resistors in place of capacitors! Jesus, I'm marveled that these multicarts manage to work in stock form.
Should I clean the mess? With what product though? 90% alchool takes forever to remove this thing.
Tested Puzzle Bobble on 161 in 1 and don't get the sound issue, will check my 138 in 1s later. Also will check MS2 3rd boss later too! Not sure about BIOS, I only use Unibios and always set to European or US and always English on any multicart.
