What is the going rate for a great condition front loader with USBCopyNES installed? I am looking at RetroUSB's AVS and think I might make the switch. I don't want to ask an outrageous price, but I'm not looking to give it away, either.

I missed an AND that made the bus conflict prevention only work for banks 0-7. Try downloading this again: https://dl.dropboxusercontent.com/u/883356/U5ROM.BIN It works! Thank you SO MUCH for your help with this effort, without you I would be desoldering chips and fiddling around with things beyond...

I'll give it a try as soon as I get home from work!

I don't have anything I can test it with, but try this with http://code.google.com/p/usbcopynesblue/ Put in PLUGINS folder: https://dl.dropboxusercontent.com/u/883356/U5ROM.BIN Put in program folder: https://dl.dropboxusercontent.com/u/883356/MAPPERS.DAT It should show up under "unlicensed gam...

The places you'll need to modify are probably near this chunk: crc_fail: lda #3 ;crc failed, determine size of normal UxROM game jsr wr_bank jsr compbank beq is64k lda #7 jsr wr_bank jsr compbank beq is128k is256k: ldx #4 jmp next_part is128k: ldx #2 jmp next_part is64k: ldx #1 And this chunk: ;PRG...

No sorry I won't share the rom, that'd take the fun, challenge, and legitimacy out of it ;) Have a soldering iron? I have a hacker solution for you. Lift the A18 pin (referenced from the flash chip's datasheet) on the PRG-ROM from the PCB. Connect it to GND. Dump it as UOROM 256KB (that's your lowe...

There's no need to build a new dumper when you already have a perfectly good one. If it's just plain UxROM all you need to do is modify and reassemble the plugin for it to check for and dump the larger size. I know that sounds so simple to many of the members here, but I'm just not sure how to go a...

I have looked at the kazzo project page and can't really justify scratch building the device to dump one game I sent you a PM.

Here is a pic of the board for anyone who might be able to help.

Are you playing the demo rom or a full rom? I thought I had found the full rom on a site, but when trying to input a password it gave a message saying the password feature couldn't be used because it was a demo.

Well, this is good way to learn, if you want those abilities. Otherwise, I dunno, maybe there's somebody here you can mail it to that would like to take on the challenge. I think I could do it, and it would be a fun challenge, but my interest in this is only at the spectator level. I'm a little cur...

It's not really a UOROM. Probably something equivalent but with registers or values scrambled in some way to prevent exactly what you are trying to do. Options: 1. Use the CopyNES debugger to walk through the startup code. This will be very, very slow, but you might be able to get to the bankswitch...

I'm a noob when it comes to modifying a script. Is there a recommended program for opening and editing the UNROM.BIN file? Also, what would I need to change in it? It's not a script file - it's a plugin . You would need to download the ASM file, edit it (it's 6502 assembly code), then run it throug...

You'll need to write your own dumping script. It should be only a small modification to the one provided by boodgod here: http://bootgod.dyndns.org:7777/plugins.php I'm a noob when it comes to modifying a script. Is there a recommended program for opening and editing the UNROM.BIN file? Also, what ...

I am using a USBCopyNES to dump a copy of a game that I own. I do not want to say the name of the game because I support the developer and don't want to get requests for a rom if I am able to dump it. I just want the .nes for my own personal use. The game is 512kb and I think the mapper is either Ux...
