Ahh, gotcha. I'm a little confused by the weird change in buzz I get when I press A or Start in LSDJ (it happens when actually selecting notes, but not during playback), and it plays through the speakers, so there's feedback through the speakers related to my input, even when the sound is off.

Gotcha, I'll have another look at the soldering-- the pro sound definitely works, the ear I can hear through has great sound quality! I just gotta fix the connections.

Yeah there's something to do with a power saving feature implemented in LSDJ that causes that. When playback starts, that feature is turned off and it should not buzz when you press buttons. Someone correct me if I'm wrong, but you're still well within the limits of normal. I mean a gameboy was designed to play tetris for a 10 year old with crappy headphones so the audio isn't perfect. You'll likely want to do some noise reduction in post-processing.

Glad that worked. Did you realize that there are three colors of LED's on that panel, so you could hook one or all of them up to create different colors?

Switch the red and black wires and see what happens

Super GameBoy is gone. One powerpak still available.

Seems like the ASM ones had a built in resistor.

PDF Format had one of the best channels on youtube of all time. Along with that video, here are my 3 favorites:


Also, I believe the taco references are talking about using a 3.5mm jack for a midi port on a gameboy dubbed taco midi.

Looking through the mGB source code tonight and found this gem: https://github.com/catskull/mGB/blob/ma … mgb.bat#L1

I'll be loading it with the translation ROM of Megami Tensei Gaiden - Last Bible II to add to my MegaTen collection.

How will you flash it?

Could you just modify the JP instruction at 0100-0103 to go straight to Trippy H instead of the normal menu location?

I'm out of my league here.

I could change key_repeat to something like 6 and recompile?

If the button repeat speed was slower it could actually be useable,haha

Inpuhandler.h, line 32:

/* key_delay and key_repeat values are measured in vblanks */
UBYTE key_delay=6,key_repeat=3;
UBYTE key_delay_counter,key_repeat_counter;
UBYTE new_keypress;

Do you think thats the variable you want?

I made a few aboys myself, but this sure is a lot easier and less messy wink
Did the pro-mini boards ever get made? Since I still have a few of those...

Nope. I sort of abandoned that idea (for now) because the UNO clones are pretty close to the same price as a pro mini clone, and the boards aren't really that much smaller. I'd probably do an SMT aboy before I do an pro-mini board because then the boards would get REALLY small. I probably wouldn't sell those as kits though, so I need to figure out assembly with a reflow oven so it's on the back burner.

Also, just an update for everyone! I just got the PCB's for version 1.0.1 in the mail today! This revision fixes the link pinout problem. Everything else is the same. So if you were holding off buying one, it's a great time to finally pull the plug! catskullelectronics.com

Plans for the next revision are removing the screw terminals (I don't think a single person has ordered a kit with screw terminals lol) and adding a PS/2 jack.  That's not going to happen for a few months though, so don't hold your breath.

Thanks!
