Will that work? Zelda uses onboard chr ram where as skrom has chr rom.

Re: Help with Legend Of Zelda repro

Yeah sorry I assumed this was snes. I should have read it a little better. Can you use a normal ntsc donor? If you can nes open golf and golf power should be good donors. You would just rewire the prg as follows. SNROM (mapper 1): Bend up pins 1, 2, 24, 30 and 31 (or cut tracks 2, 24 and 30) Solder ...

Re: Help with Legend Of Zelda repro

I'm not very familiar with what you are doing but depending on the size of the translation couldn't you just split the rom into 2 files and toss on two 27c801 and swap bin them and toss on a troy aikmen cart? Or is it too big a file for that?

Re: what's wrong with my Hard Drivin repro?

Yeah, you're a bit more advanced in this than me :) While I have learned a lot and come along way I only started learning about anything 7 months ago. Heck back then I didn't even know what an eprom was or for that matter the difference between a resistor and capacitor lol. It's interesting to learn...

Re: what's wrong with my Hard Drivin repro?

R6 left goes to Rambo 15 and right is to ground. On back side it shows the solder pads for p28 which must be hidden under the rambo chip going to rambo 40 and if jumper would tie in 39 as well. The front c28 if you jumper it would go to Rambo 22 as is goes to Rambo 40 100_2032.JPG Here is the crash ...

Re: what's wrong with my Hard Drivin repro?

Just curious it doesn't really look like a glitch but when I crash for game over the glass breaks with number and such in it before it goes to game over. Everything else looks fine, do you get the same?

Re: what's wrong with my Hard Drivin repro?

Ok had to pop out the resistors for accurate readings. R1 goes to Rambo 19 and 20 front cart pin 31 all way to right and back cart pin all the way to the right, basically all the grounds. R2 goes to Rambo 2 The middle section between R1 and R2 goes to prg hole 24. R3 left side goes to chr 24, right ...

You just want continuity correct. I can do that real quick. You want just the whites or the yellows as well?

Re: what's wrong with my Hard Drivin repro?

Yep that fixed it. Just moving that resistor up. Thanks. If I would have seen that I would have tried it lol. I thought the klax board had the resistor to the right instead.

Re: what's wrong with my Hard Drivin repro?

Now I see what you are referring to w/the resistor under the 7432 I totally missed that it could go higher up. I'll try that.

Re: what's wrong with my Hard Drivin repro?

This is all set-up original except the top white resistor I moved from R2 to R1 and just never put it back like I did everything else. The white resistor under the 7432 I did not touch. I thought it may need to be moved but the board is actually slightly different when you look at the klax. While I ...

Re: what's wrong with my Hard Drivin repro?

Hi, I was wondering if you guys had any play issues? I used a rolling thunder cart this board: http://bootgod.dyndns.org:7777/image.php?ImageID=1657 prg pin 2 is already mapped to Rambo pin 2. I connected prg 24 to prg 16 and I did chr 30 to Rambo 22 Everything loads fine and plays fine except for i...

Re: Loading nes games backwards. Are they fried for good?

I'll be damned lol I just tried it a few more times and nothing but the picture was not pink anymore it was gray. I cleaned it again and it powered on. Unreal lol. Maybe those corroded pins were casuing the problem. I still want to know what that guy did to my games, back to square 1.

Re: Loading nes games backwards. Are they fried for good?

I'm telling you I fully tested a game and it worked perfectly and after I put it in backwards it was shot. I'll grab another game and make a video to prove it lol. I am thinking of pulling the chips and dumping them to see the code. Edit: Mind you I don't know what exactly is wrong w/the games he re...

Re: Loading nes games backwards. Are they fried for good?

Well in case anyone was wondering. I took Donkey Kong Classics (one of the games he returned) and swapped the mapper with JE QB and no go, I then swapped the cic, and no go. I then put the dk mapper and cic on JE QB and that works so basically the prg and/or chr chips are shot. It "could" be the pcb...
