Weird then, the code seems to increase Y to go into the air >_>

Anyways, the exact values are as follows:

• Top: 128
• Bottom V28: 352
• Bottom V30: 368

It doesn't matter in my case because the sprite rendering routines fix the coordinates so entering 0 gives 0 and not -128

To be honest another impression I got from that code is that you were considering Y to be positive upwards, rather than downwards as I do.

EDIT: updated, fixed another issue. Silly me ^_^'

It won't work unless both PlayerForce% and Gravity% are negative. You're checking against a ceiling, not a floor (PlayerY% <= Ground%, should be >= instead). EDIT: it was respect to TmEE's post :P EDIT 2: notaz was right... ARGH. OK, ROM updated, through I think I'm going to change some speeds...

your game works perfectly on MD YAY! :D and I can't understand your ASM code... and I don't know C.... Jump code: if the player is on the floor (player's Y = floor's Y) and the up button is pressed, jump (set a negative gravity). Gravity code: first increase player's Y according to the current grav...

That game demo looks nice. I think the jumping bug is some stupid Bxx error.... my particle stuff did all kinds of weirdnesses until I found that one Bxx was wrong :) But then again, I have no idea how your stuff is written so..... anyway good luck. This is the only piece of code that has to do wit...

BIOS hack? (remember the BIOS initializes the VDP by its own, also it writes a bit of stuff to RAM (exactly at $FFC000) to be able to do the bank switching properly). Actually I don't care, I write to all the registers :P Anyways, that may be the cause of the warning in KMod. I just know absolutely ...

Wow :D Sweet! :D Haha, i like the perfectionism of the line scrolling background, fake dithered shadow and more ! :D Er, tile scrolling background :P Through the dithered shadow is a good one. Also check how it blinks. I actually figured it out by myself, but later I found out Gunstar Heroes uses t...

And you're wrong too, what you mean with "interrupt 3" is "interrupt request 3" (IRQ3). Interrupt and exception are the same thing in this case. People tend to say interrupt when talking about an expected trigger and exception when talking about an unexpected one (errors), but they're interchangeab...

Oh, well, here I go: http://srb2town.sepwich.com/junk/nfight.bin Very early prototype for a fighting game. Through for now you can only walk and "jump" (the jumping code doesn't do what it should, try to jump and you'll see :P). Also there's only one character, through both players already work (use...

First off, you're doing a word write to an odd address, which is in the subroutine at $0002F0 (right after the main loop). Specifically, here: 00032A : 30fc 0011 : move.w #0x0011, (a0)+ ; a0 = 00ff038e 00032E : 10fc 0080 : move.b #0x80, (a0)+ ; a0 = 00ff0390 000332 : 30fc 0000 : move.w #0x0000, (a0...

Ok, here it is. 0x00ff0391 ori.b $#0, d0 It seems to be no where.AamirM WTF, how did PC reach there?! The game never runs code from RAM. Also, ori.b #0, d0 is $0000 there, right? Because as far as I know, that very same instruction is the one that causes 3D games to crash in Genecyst (I wonder why ...

Some more remarks: Whenever you find it put here the piece of code that belongs to it. If you find it inside a bunch of subroutines that access to VDP (a lot of them unused), I know where it is :P If you find it in code that reads the joypad... then what I've heard about NBA Jam 96 being able to acc...

Well, I don't like to deliver bad news but your program will not run on a real Genesis. That is because your program is generating an address exception. If I turn it off the address exception emulation then it will run just fine. So there is just another example that Regen is more accurate than Keg...
