awesome
i would buy it

i don't know why you are saying i'm trying to build bootlegs to sell them :? i never wanted to do something like this and i don't understand why you claim i would do something like this :x i like contra have played through it a hundred times and then i found this version with some neat video sequenc...

hi there, does anyone have a copy of the patch because i can't access the download page.

thanks in advance

@jonnymopar i would say, you should test it with the tkrom-10 as i learnd the higher a board rev the better is the compatibility of a game on it ;) i don't think changing the sram of the tsrom-01 would increase the compatibility of games playable on it because the mmc3 chip has some bugs which were ...

if you have modded the tsrom to save your data like me then it would be the best to delete the data with (i think) up+select at title screen. i had the issue too and deleting existing data on sram helped. another problem could be the board version. i use tsrom-08 from mario bros 3. you could try usi...

I made a pretty small one using an atmega8 and a 8x flipflop to test things out for the NESDEV1. It really doesn't have a limit to how big the memories can be if you just keep adding flipflops to IO extend. I just adapted this I2C programmer to work with SRAM: http://xldrx.com/xl/EE-Prog.html Here'...

Hi Guys, I need some help: I would like to build my own (really portable/tiny) USB SRAM programmer, which can at least program 6264 SRAMs, but I'm not talented enough (or have got any knowledge) on how something like this is realizable. So, I hope some of you who are familiar with this topic can hel...

okk i've solved it thanks to l_oliveira^^
somehow the gnd pin of my chip bend up itself...
but now it works:)

connecting /we to vcc didn't solve the problem.
any other suggestions?

really well done game;)

just a question:
my w29c020 won't work for unknown reason.
i've tested other flash roms (29f010) on the same board and it worked but the windbond w29c020 (with the exact same pinout) won't work...
any ideas why?

ps: my chip programmer says that they are equivalent to ae29f2008

i'm using a willem (i think it's the pcb 3 model) over parallel port (had to add it) on win7 64bit^^ no problems so far. i bought it for 30€. if you want to use it over usb, there are also willem parallel to usb adaptor specialy build for willem programmers. it supports a whole bunch of chiptypes. j...

thx for the advice but i think the cart uses for sure some glop tops and i think it hasn't the right mapper. it's multicart so it has to be a mapper something around 150 or somewhere for multicarts

i read that mapper 163 is used to get bigger roms working (i think the mmc3 only supports up to 512kb per chip)

ohh didnt got that at first I've already done so
