idk a fair price, two chips are involved though. vid below is this cart

I made some source changes in the initialization to fix a problem I was having with the palette and the initial text display by writing the initial palette directly to memory rather than relying on the loop. Also I used all 8 screens for actual game screens, as such the initial text is being written using chr table byte string as the initial screen didn't have the text in the same location as glitchNES' original initial CHR bank.

hmmm very odd cuz I've had 0 issues with NTRQ on carts

could possibly be related to the speed of the chips you're dropping in, farfetch though

Thanks for the quick reply!

Yes, I am using 27C010 in several donors. I've tried Bard's Tale, Shingen The Ruler, NES Open, Ultima Exodus, and one other I am probably forgetting at the moment - all with the same behavior. I'll test the battery removal next...I never thought of doing that.

I should mention I have similar results when using PR8/Pulsar in donors as well, although they barely even turn on.

I always use Zelda's for donors, fwiw

are you 100% positive your chips are flashed correctly? have you built donors prior to this? You did strip the NES header prior to flashing right?

I read somewhere that some SNROM boards (Shinren the ruler was the example i think) behaved strangly with NTRQ. I've built 6 NTRQ carts to date and all have worked without issue aside from dirty contacts requiring a lil jiggling in the slot to get a proper connection. I guess it's possible the SRAM has junk data which is messing up on load, you could try pulling the battery and waiting for the chip to drain. Are you using a 27C010? If you're using a 27C101 the pinout is slightly different, I believe you have to bridge pins 31 and 32 in order for those to work properly but don't quote me on that.

for reference here's this pcb:

pin 31 is lifted but not attached, should've just clipped it

price would probably be a lil higher than NTRQ because I'm probably just gonna source donors through some JP contacts, rather than go through the whole SNROM > SXROM bit

would there be any interest in some PR8/Pulsar carts if I were to construct some?

No, the active chip musicians in Austin are organized into a planning committee and work as a group to book shows; that's what I mean when I say "we" in the context of booking and promoting.

we have a Facebook page and a (currently underused) Twitter (@txchipmusic), and we're about to start working on a website.

I don't really have any formal releases at the moment, personally. I need to fix that. tongue

I'll definitely keep you posted, though!

cool man, let me know if yall ever come down here / need help setting something up down here, I hang out with a bunch of dudes from a regional electronic label

I'll double check all used donor carts later tonight/test NTRQ, sans wire.

Not that anyone cares, but I gotta say I prefer donor boards over new pcbs, simply because it's one less cart in a landfill/one less cart being produced. There's thousands available, why not use what's already there, you know?

Honestly I prefer donors mainly because I can source them for basically free, whereas if I order an unpopulated board from retrozone I need to also add in a ciclone for the lockout chip, extra chips for mmc1, etc etc etc. Better off just using a board that's already populated, its not like the rewiring for the EPROMs is that over the top. If retrozone was selling boards prepopulated so that you just dropped in chips and went your happy way, then yeah i'd probably use them instead.

Also I don't like that retrozone's NROM boards need two separate types of chips, rather than just using two 27c256 I have to use up a 27c010 too? meh
