Could you please post all errors generated by avr-gcc. Should have used the makefile. D'oh! It's working now :) Glad to hear it make sure you replace 524288 with 262144 in both programs so it works with the smaller capacity flash chips. Also for stuff that you should be real careful to do is not mi...

Sorry for the double post, but I felt that this deserved a bump rather than an edit. I compiled the avr and host pc programs successfully, and my stuff from digikey arrived today! I am ready to roll once I wire in the 74hc595s. Is there anything I have to be really careful not to do? e.g. if i wire ...

Do you want a TV with 'v hold' and 'h hold' or are these different? I know a guy with lots of these; he's giving them away
But not an Apple II monitor. Sorry.

Could you please post all errors generated by avr-gcc. Should have used the makefile. D'oh! It's working now :) Now when my 74hc595's get here I can try it! Also, I did end up ordering two sst39sf020's. They supposedly have a memory retention twice that of the 29c020's (according to the datasheets)...

Note that I used avr-gcc instead of the arduino IDE to compile this if you do not have avr-gcc it can be modified with ease just change int main() to void setup() and add void loop() {} at the bottom of the program and I think it will compile just fine in the arduino IDE. And here is the part that ...

About dumping the chips... I just committed a patch to my repo for both the computer side and arduino side that allows for the dumping previously it would always go into write mode which would erase the whole chip now it will go into dump/program mode based on which program on the computer you run....

yes however I hate to see part sacrificed. I don't think it is worth it to destroy a computer just for an NES game. Don't worry :) I will dump the chips to flash images first. And I found these beauties in a pile of junk in a factory corner. I have the pentium II's and III's and in the future I may...

Can one make a MMC3 board into a TKROM board without too much effort? Perhaps you mean, can you convert a TSROM (no battery) into a TKROM (with battery)? Both are MMC3 and identical aside from battery backing. If you splice in the battery baacking circuit from the wiki you should be able to make so...

...This is spectacular. I always thought that since a Commodore VIC can be modded for rgb, a NES should. I must have been right for once! :D

I made a sst39sf040 programmer using an arduino uno and 3 74hc595. The sst39sf040 (cost $2 in single quantity at digikey) is cheaper than some eproms and does not need 12v only 5v and it is still in production and it does not need uv light to erase. Here is the wiring: Pin refers to the numbering o...

I am on an extremely tight budget and need to have a way to develop NES games, but I cannot spend more than $30. I have an Arduino Uno and an Arduino Leonardo, some 4021 Shift Registers, and I want to know if that is enough to make an EPROM burner / programmer. I need to be able to burn 256kb EPROMS...

Sorry for very slow response; I live in Fort Wayne, Indiana. Frontier is my ISP. I am redirected to webring.

It's good for creating data later, as hacking shows you have somewhat of an understanding how data is stored and read. :) Still, just look at a page like http://www.obelisk.demon.co.uk/6502/index.html to learn 6502. It explains instruction, addressing modes, registers, all of it. :) That page is do...

...play with FCEUX's PPU debugger... I do play with the FCEUX Debugger. I did a simple hack to disable piracy protection in the EarthBound Zero Rom: http://forum.starmen.net/forum/Community/PKHack/I-found-out-how-to-fix-anti-piracy-Screens-in-hacked-EarthBound-Zero-ROMs-by-Changing-a-single-byte Al...

"Hello World" isn't typically the first NES program people make, because the NES doesn't have a built-in font or a BIOS with a routine to print text to the screen, so "Hello World" gets quite more complex than in any modern programming language. People often show colors or sound...
