The Name "Tennis For Two" would work and I don't think there is a trademark on it or at least
not one that could be justified as that is a pretty common phrase.

No, pin 22 on a 27'512 is /OE. It needs to be low for the 'PROM to output data.

ok so to the ground it will go!

It's got a 28pin package but is using 128k on the prg which confuses the hell out of me. That's perfectly normal. It's the JEDEC-standard 128KiB 28-pin mask ROM pinout, with a single output enable. Pin 22 is A16. OK, I am just more familiar with 32pin 128k pintout is all. So if I was using a 27512 ...

Hey, I've looked but can't find a pinout for the TQROM pcb. It's got a 28pin package but is using 128k on the prg which confuses the hell out of me. So I'm assuming the pinout must differ from more common nes pcbs. I only plan on using it for 32k or 64k of CHR and 64k of PRG and I'm taking the CHR R...

Those pcb lines break really easy as those boards are VERY low quality. I'd check your connections on the chr lines and\or reburn your chr chip.

The 2600 couldn't do that but the 7800 might have been able.

Love the big image in the first post. Very Doki Doki Panic of you

And now the world is perfect

To add a second request to anyone reading, myself I was wondering
about a schematic for replacing a 16k SRAM with a 64k SRAM. I have
some NBA TE carts that would be alot more useful if I could add more
ram to them.

3. Buy a better programmer cause that one is weak.

According to various resources, including this atariage thread , the first Atari Flashback was not 2600-on-a-chip hardware like later revisions but was infact a NES-on-a-chip clone, specifically the Novatek NT6578. With this in mind, has anyone torn one of these apart and done the usual clone syste...

I've wrote guides before for noobs and some of the more seasoned vets asked me not to post them as they just end up in the hands of those that are only looking to sell repro's for $100 a pop. So start by making a bunch of "How to make Holy Diver Batman on XYZROM" guides, putting them on t...

I voted yes for different reasons. 1) It would be good to have a section of the forum for "noobie", "learning" and\ or straight up "I wanna pirate this game an profit" users which will keep such threads from clogging up sections of the forums where much more versed prog...

now if it could only be mapper hacked to something a little easier to get
onto real hardware

Yes I got your message, looking in some other threads right now too as
I think I recall a similar topic from another user being addressed before.
