Here's the WIP v 005. Note Entry screen is only partially implemented so nothing works properly in there. I edited the startup code a bit so maybe now it will work, but maybe not. If you do get it to work, dpad navigates, c+dpad edits values, and a+dpad ...

Another user of this board "Jazzmarazz" has tested the YMDJ demo on real hardware. This is what Jazzmarrazz said:

"To be more descriptive, the TMSS shows up on screen and while it is on screen, I may reset the console how ever many times I care to. Resetting the console makes the TMSS flash. If I ...

I suppose I also should have said "EEPROM" anyhow. Also, do you think you fixed the hardware bug in v004? Keep up the good work!

Maybe, maybe not. If I remember right, the first VDP register was set to #0x20, when it should have been set to #0x14 (horizontal interrupts and palette select was ...

I guess I'm just used to ROM meaning Read Only Memory.

Well the issue I had and fixed in relation to this topic, was actually several. Mostly with my tile drawing loops. One of them was harmless but was drawing garbage to Plane A underneath the bottom of the screen, fixing my loop counter fixed that. Same thing with the loop that draws the FM1-PSG4 ...

I've learned to keep a very close eye on the ram output in Regen, and an extra close eye on my stack. I'm trying to plan ahead for how much ram I need for all the data tables for the Song/Chain/NoteEntry/Instrument etc screens. It's possible my current method for arrays/tables might be a little ...

Watch out for address errors. Those are the bugs I run into the most! Tell me about it. This one was really tricky to find, I actually ran into the problem code by mistake (luckily).

I ran into another issue today, I was tempted to ask for help but I stuck to it this time. I'm not going to learn ...

I'll test anything you throw out there. I don't have an everdrive, but my flash ROMs work just the same. Cheers

Flash ROMs... so basically every failed test is a wasted cart/chip? They're not rewritable are they?

Well anyways, the chain screen is done. All the data arrays for the Song screen ...

Hey, thanks for testing. Since I've posted v002 I found a couple of problems with the startup code and fixed them, though there is probably more... in fact one of them probably has to do with the ROM name, I'll have to double check everything. It's probably an easy fix if I can figure out what ...

I normally would help out, but I'm so focused on my own projects. I second what TmEE said. I recommend FastTracker2, or Milky tracker, but you're going to need samples to even work with them, or you can draw your own in the sample editor. Did someone already mention Deflemask? I didn't read the ...

I'm glad you're finding it useful! Just make sure to proof read everything and don't take anything I wrote as gospel, it's more of a diary than a tutorial and there are a lot of mistakes.

Without a doubt. I'm using the startup code you made directly in the program, although I could probably ...

I actually think I may have figured out the problem. Bugs can be tricky to find!

Is there something special about anything in this block of ram space???
Before going further, I'll say that I already found a workaround by writing to 0x00FF0045E. But when trying to load a long array of bytes seemingly anywhere from 0x00FF03F8 to 0x00FF045C as a starting address I get an odd crash ...

Nice work. I'll slap it on a cart and upload a pic of it on real hardware for you. There should be no differences since it doesn't really do anything yet. :P

Hello again. There could be some hardware unfriendly code in there and if there is, it'd be really nice to know before I get really deep ...
