?????????? D1 as in diode #1 in your diagram, not the data bus. This is what your circuit should look like: http://img262.imageshack.us/img262/3150/sram.jpg Don't do anything with CE2, it should be controlled by the MMC1, a battery backup circuit or tied enabled (as should /CE). Oh OK, i thought ab...

OK. I swapped those wires and graphics are worse than before.....

YEAH!! I've nearly done it!!! :) But, nearly..... Don't look up at the early photos, because i haven't cutted some tracks on this pirate PCB and graphics was really crapped :) . Some new screens with beautiful graphics from original IREM's Holy Diver ;) : http://img204.imageshack.us/img204/4431/dsc0...

Well, OK. So, i removed this 10K resistor, and, I must add a 1K resistor between PRG D1 and GND??? So, I added this resistor and game freezes after pressing START...... EDIT: Oh sorry, I didn't read that correctly, you say AFTER ;) . But, I connected this 1K resistor between D2 and GND, and game aft...

If I add a resistor 10K, 1K with 5% tolerance, 1% tolerance whatever, before or after DZ1, effects are MUCH WORSE than before..... Effects are much worse, if I add any resistor from battery..... But this is weird, because if I connect a battery with this scheme and add a 10K resistor before DZ1 in k...

Hi guys!!! I have problem with connecting the battery on my zelda 1 homebrew cart from a pirate famicom cart...... I connected the battery by this scheme: http://img81.imageshack.us/img81/2587/mmc1.gif and I added an extra resistor 10K with 1% or 4% tolerance between WRAM /CE2 pin and Ground. My fri...

YEAH!!! Big thanks guys!!! :) I connected CHR with another 74LS161 from this diagram, but to PRG i connected D4, D5, D6 and D7 pins :) . Now I made a dev-cart. If something will be wrong, I will rewire this ;) . http://img269.imageshack.us/img269/2482/holy3.jpg http://img210.imageshack.us/img210/868...

Well, you are saying, original starfox is not good??? But, on this tutorial guy uses a stunt race FX cart has got superFX chip and this chip is the same in starfox PCB.... http://en.wikipedia.org/wiki/Super_FX So, it is not possible to do it??? I have got DOOM cart in PAL, but this cart is very expe...

Hi guys!!

I saw this awesome tutorial at snesdev :
http://snesdev.romhack.de/sf2.htm
and I have 1 question: can i do it from original starfox game??? But, I must get the 512Kbit SRAM, but, I think, on the PCB starfox I can replace it . Or, I must rewire something, add or, whatewer???

YES, but, this version is buggy....

WOW!!! I recorded an original holy diver PRG on my EPROM 128KB, I've started it on my UNROM dev-cart and i can really play it!! But with crappy graphics, of course ;) . But, I don't really understand you..... CNROM can address max 32KB CHR and there is a full pinout of CNROM board: http://www.vulome...

Hi!!

I want to build a cartridge with original Holy Diver . I think, it is possible to do on an UNROM board. But, I don't know what's really needed to build a cartridge..... Can someone tell me about this??? Or can someone make a full pinout??? I will be very thankful!!!

Hi guys!! :) I want to create 2 cartridges , Legend of zelda and Zelda 2 from my famicom cartridges and i have a question: where i must connect pins 20 , 22, 26 and 27 from WRAM memory in both situations??? Please help me. Thanks!!! I'm not English so I can't speak English very good, but, please und...
