well I tried connecting it to the composite input of my tv. iirc pin 2 has composite output so I tried connecting it to my tv. It gives a nice grey screen, the floppydrive tries to boot, after a while it stops, but the screen remains grey.

Hey people, I just unboxed an atari 1040stf I got. when I turn it on the floppydrive constantly seeks activity and the power led turns on and off. No video on screen...... any idea's? [EDIT] Correction...all I get is grey screen

this is very cool..... I'll be watching this

hey, what kind of graphics and sound alterations are you trying to do?

do you happen to have a gamegenie or action replay? if so, just put it on there backwards, put it in your snes and power it on for about 30 secondes... if I recall right.

How are games programmed in?

is it PAL or NTSC ? How about the consoles you try it on? What region are they? Do they have disabled CIC's ? 50/60 Hz switched your SNES-es? Have you tried clearing the game memory (if it uses a save function)

The first one is awesome!! Really has the authentic POKEY sound.... I like it. Reminds me of the "gets-stuck-in-your-head" song from that demo DRUNKEN CHESSBOARD.

1541EMU isn't able to run anything......I've tried that. Speed/Custom loaders still are a problem, and the problem is called timing. Timing on the LPT port just isn't accurate enough. The best thing the topic started would do is buy a 1541-Ultimate. That's compatible with practically anything you feed it (not even mentioning G64 files)

xe1541 can be used with 64HDD, but that thing doesn't support custom/speedloaders and such. The best thing you could do is build either an XE1541 cable and use Star Commander under DOS to transfer D64 files to floppy or an XM1541 which can be used with CBM4WIN under windows XP. The XM1541 is build the same way as the XE1541, but with 2 lines hooked up in a different way.

if I had a jag, I would try.... but why the stankboard?

I was talking to a friend of mine yesterday and he was looking for a way to play roms on his gameboy (color) I started searching for my gameboy games, took one that I wasn't playing and took it appart. A maskrom and a mapper/bankswitching chip were there and I searched the internet some more, looking to find the maskrom pinout and the the cartridge pinout. I managed to find it, so I took my multimeter and checked if it was correct.....it was This afternoon I desoldered the maskrom and soldered some wires in it's place....as you can see below: DESOLDERED MASKROM SOLDERING WIRES IN PLACE After a short break (my wife finished diner) I finished the soldering and made sure the wires would stick to the board by putting some hot glue on them THIS IS THE CARTRIDGE WITH THE WIRES COMING OUT: To test the thing I took an old pc motherboard with an eeprom as bios chip and flashed it with a gameboy game. TIME TO TEST THE THING : http://youtu.be/oOfdjv1WqzE The gamyboy I am testing it on is a gb advance SP. Classic gameboy games stick out a lot, but this one sticks out a bit more because the cart is extended with a pcb with an IC Socket so the eeprom can be inserted. I want it to run on regular flasroms in the near future and all I need to do now is build a programmer for the thing so roms can be changed via the carts directly

Yeah I have looked at it, but I am a hardware enthousiast and I wanted to see if I could build an SRAM cartridges that is programmed via my pc when it's interfaced with an arduino (using flipflops to connect the extra adresslines)

I have been google-ing for the last hour and a half trying to find out if colecovision uses bank switching with some games. I am trying to build an SRAM cartridge so I upload my own created stuff to an sram chip (and of course try games on real hardware before buying them). So far I've created one game called space defend and it was fun playing it on emulators, but now I want to try it on my actual colecovision. Do I have certain limitations when it comes to filesize of games on my coleco or will it take 32k without bankswitching ?

I once created a Pong game, driven by a PIC and drawing it's power from 3 AA batteries. It was a nice project.....must be around here somewhere.

I'm not finished with my Videopac yet. Also gonna add the AV-out and Powerswitch later. My problem is.........time.............and having a lot of projects.

That's why I won't do a pot meter as a final product in the first place. Just a POT on the bare PCB, but when I found the sound I liked....I would have measured the resistance and placed a resistor with that (or as close as it gets) value so I could really close the cart again. I know they can't be opened without damaging the label. I allways damage the labels, but after finishing up, I just print a new label just to make it look good again

I would have done the same thing as the person that reacted the first. I would first measure resistance with the pot meter and after I got the right pitch (like this....sort of )After that I would just replace the resistor and put the thing back in it's case again. Replace the label with a label which isn't messed up by the screws, and enjoy my pitfall 2 game again.

uhm...what about the pot meter settings? and did it happen to be a thompson drive? If so, these are the most terrible drives ever used in the original xbox @topicstarter: If you can get a lens and you're technical enough, i'd replace the lens. If it's a thompson drive, I would try finding a SAMSUNG drive for the original XBOX. That's the best drive you could get.

If you are talking about replacing the dvd-drive totaly....you have to flash your drive key to it. The dvd-drive's laser lens can be swapped by a new one without any problems. I did 2 of them myself. They only thing you have to remember is that a brand new lens ofter comes with a little blob of solder on 2 pins that has to be removed. It's a protection for something, but will ruin the laser when it's powered with the 2 pins connected together. I had 2 Lite-on drives with bad laser-lens which I replaced with succes. 1 I replaced with a brand new laserlens, 1 I replaced by a lens from a BenQ drive which happened to be the same....lucky me. The 2nd drive is gonna be my spare one.

Games giving problems would only involve import games. Example: Buy an NTSC adventure of link and put it in a PAL console. The screen scrolling on top of the screen (life and magic bar part) acts weird and the pitch of sound is a little bit of and slower. Many games work good, except for the sound being slower than it's supposed to be. I played several imports on my PAL nes (US and JAP famicom games with an adapter to 72pins) and never bothered the slower sound. Some import games (mach rider, Challenger, F1-RACE) are really unplayable....but it's not a big deal. About the mod, you really can't mess it up. It's the first mod I ever did in a console, and after doing the first, I ended up modding ever NES in the house (I was about 18 or 19 years old). Just open up your NES, locate the CIC chips, cut pin 4....that's it Some people feel safer connecting the pin to GND with a wire, but I never did (left it floating) I did solder it to GND in my SNES, but that's another story.....

with an arduino it can be done

Hey People. I have a videopac G7000 which had hardwired joysticks. 1 Joystick was a little broken so playing it was a pain in the ***. Yesterday I took it from the attic and hooked it up......not working!! I took it appart and cleaned the cartridge slot. Also noticed a weak soldering joint so I took my soldering iron and took care of it. Tested the console while it was open and it worked again!! Since I still had it downstairs today I decided to take out the hardwired joysticks and replace them with DB9 ports. I had 2 of them in my partscase, waiting for the videopac to come from the attic. After removing the first joystick and soldering the DB9 port in place, I tested the thing while it was still appart....like taking candy from a baby! Had an Atari joystick ready and hooked up, and I was playing with it like the videopac allways had the DB9 ports for the controllers. My girlfriend interupted me to go shopping, so the 2nd controller had to wait. When we returned home, I took off my jacket...got the 2nd DB9 port and soldered it in place. I took my THE ARCADE controller and hooked it up.....also working! HOW WONDERFULL!!! The controllers that were originally in there are now resting in the shopping bag I keep my Videopac in......waiting for me to decide what to do with it. After completing the mod and putting the videopac back together, I decided to play a little game and post a short vid (16 seconds) on youtube. http://www.youtube.com/watch?v=aPNW9D0vzq0&feature=youtu.be In relaxmode on my chair, playing Pickaxe Pete on my videopack

contact Keoni19, send it over to him and let him dump it. He has made a dumping device that's interfaced to an arduino which can just dump carts without opening them.
