Re: Mickey & Donald Magical Adventure 3 (J) won't boot on US

I don't understand hexadecimal yet and wasn't sure how to tell people that specific spot needs to be changed. After reading what you said lidnariq, that is correct. Thanks for simplification and quick lesson on address locations as well:)

Re: Mickey & Donald Magical Adventure 3 (J) won't boot on US

Change this byte in the patched rom and it should boot without problems, http://imgur.com/fPGKrBW Any guesses as to why Ucon64 misses this one though? The way I found the address was I tried the (J) [t1] good name of the rom(bad checksum) and it played fine on a real SNES. Did a file compare and the...

Mickey & Donald Magical Adventure 3 (J) won't boot on USA?

Tried to burn the RPG1 translated version of Mickey & Donald Magical Adventure 3 and play it on a USA SNES but it only shows the translation group's intro and then goes to a blank screen. Then tried the -f operator with ucon64 to remove any possible regional protections and it then says found 1 patt...

Re: Can you swap out a 64k sram with a 256k sram?

Here is how I got my high rom 256k sram cart to work. Don't mind the jump on pin 17 of the sram as it is not needed. This was for Brandish 2 using a Madden cart, I'm not sure if others are the same.

Re: Donkey kong competition timer-- how to change

Zsnes has a cheat search tool but I think that's only for values in the snes ram. Maybe you could use a corruption tool on different address sections to narrow down the location of the counter?

Re: Best programmer for SNES carts?? Maybe GQ-4X??

Wish I knew how to code a microcontroller to program a chip, maybe I'll try and learn for this reason. In the mean time I picked up a GQ-3x and have a question for anyone who also has one. Does the Power Led light on yours light up green when just an external dc power supply is connected? Because mi...

Have been wondering the same thing Ice Man. A 12MB Ultimate Mortal Kombat Trilogy reproduction would be fun to wire up.

Re: Best programmer for SNES carts?? Maybe GQ-4X??

Willem 5 has worked on everything except 29f033C for me, but I don't think this programmer supports those. Try and reflow your flash leads if you're not getting a successful burn.

Roms and mirroring.

Read about some games, like Megaman X and Demon's Crest, that require the rom to be mirrored properly otherwise copy protection kicks in. But aren't those games 2mb in size anyway and would fill a 2mb chip completely? Could other games like say a 2.5mb or a 3mb game require to be mirrored if they we...

27c801 willem pcb 5.0c settings.

The chip verified as empty fine but received an error at the end of programming. Are the jumpers for pcb 5.0e and pcb 3b supposed to be on 3 setting like I'm thinking? Here are the rest of my jumper settings. Also for the device select is it '27c080/801 (PCB3)' or something else? http://i.imgur.com/...

Re: My first repro wont boot.

Thanks for all the help you offered Mark. Figured out what it was, had my a21 and a19 lines swapped on my tsop programming adapter.

Re: My first repro wont boot.

Continuity test checks out. Wonder how I would test if it's a reverse package. Should an ohm test with an unmounted tsop on the two VSS pins show continuity? Edit: Regarding the WE line, yes that makes sense, though pausing the erase window timer seems easier than tying a wire from the willem to the...

Re: My first repro wont boot.

It's interesting you say that because my chips erase routine times out normally for me. I have to drag the program window around a bunch causing the countdown timer to freeze and then it will erase properly. I'll go compare the original hex with a chip read hex. Edit: Well the original 4mb Killer In...

Re: My first repro wont boot.

It's in the proper orientation after triple checking. Tried to double up on the 5v and gnd lines, but that wasn't it. Tried to use a 12v 3amp dc power supply to program the willem, didn't make a difference. I even soldered shorter wires directly to the tsop adapter instead of using the ide socket, s...
