That is a 3 pin reset generator. When voltage gets below 4V, the output of that goes low. And it goes low for about 200ms after power is first turned on. You can use an RC reset circuit just fine, but I prefer those reset generators. If you need a part number I can probably scare one up in digikey or similar. I just had 'em laying around so I used it.sdm wrote:I cannot see detailed info on your schematics:

Connect AY-3-8910 sound chip to FME-7 board
Moderator: Moderators
/* this is a comment */
I have problem with mixing AY3 audio output with fc audio pins (famicom pins 45/46). When i connect AY3 to pins 45/46 i hear only NES music. I see that VRC6 carts have some resistors beetwen vrc6 and audio pins.
How to fix it??
Works, but i cannot mix channels into one output

Woot, looks good and sounds good! Glad you got it workingsdm wrote:I have problem with mixing AY3 audio output with fc audio pins (famicom pins 45/46). When i connect AY3 to pins 45/46 i hear only NES music. I see that VRC6 carts have some resistors beetwen vrc6 and audio pins.

Sorry for the thread neco, but I just wanted to thank everyone involved with this (SDM, Kevtris) for the inspiration and Kevtris especially for the help.
Uses the "PowerPak" resistor mod (47Kohm between 3 and 9 on the expansion port).
Works like a champ.

Shrunk it down to an AY-3-8912 instead of an 8910 so I could fit it in a cartridge easily.

Yeah, would be nice... but luckily, Batman: RotJ carts are easy to come by.MottZilla wrote:That looks awesome. Would be nice though if it were implemented in a full cartridge PCB with FME7 on a CPLD or something though opposed to using Batman RotJ boards but it's still neat to see Gimmick like that.
I had to go with a 8912 just to be sure I could get a board made that was small enough to fit in the regular cart without having to mod anything. The cart weighs a good bit more than a regular cart, but looks completely normal on the outside.
From what I've heard... it more or less kinda does. I don't have a PowerPak to check it out on, but I've heard that it can do the extra audio, more or less. I have heard it's a bit of a hack, but works'sh... again, no idea for sure, I don't have PowerPak.MottZilla wrote:I wonder if anyone, I guess Loopy or BunnyBoy has looked into adding expansion sound to the PowerPAK mapper for FME7/Subsoft5b. It would be nice to play Gimmick on the PowerPAK with full sound someday.
The powerpak plays gimmick + sound fine. Just be sure to download loopy's mapper pack.Scucci wrote:From what I've heard... it more or less kinda does.
