Awesome, thank you for the link. I will ask my friend to burn me a copy since I don't have an eeprom burner.
Sorry, I saw your text at 530am this morning and went "Oh, I'll reply to that later" and now it's 10PM, and neither seemed like a polite time to text. Completely spaced it the rest of the day, sorry about that.
I wasn’t getting any sound from any game but no visual issues. I had to cleaned the contacts on the cartridge (I opened it to have better access at cleaning them), once I cleaned it all the games had sound.
Yeah, the M rom has pins that are directly connected to the cart edge, if they're too dirty to be read, no sound at all. And with varying cleanliness/age/tightness of cart slots, what may work okay in mine may not be clean enough for another or vice versa. After Khatru's I've started pre-cleaning/deoxiting them before shipping just in case.
The other thing is to use a *good* power supply. My OG one (not recapped) won't boot the 161's, even stock. I ended up buying a triad because I didn't want to fuss with the OG one at the time.
I did just get back to you
@Charlie Cat , had only just seen the PM.
As for those who have missed out, or may potentially miss out: I've offered before, and will continue to offer: if folks have, or can find 2x v3 carts with the daughterboards, I am happy to make one for you for the same labor cost plus the additional two spare chips. May be worth checking with US sellers to see if they've just had some sitting on shelves, etc. Paradise or whoever.
I am almost fully caught up again. Shipped out 2 today, 1 goes out tomorrow. 3 more and I'll do another round of payment requests.
