NEO GEO Japanese Traditional Script

I'm trying to make a ninja game for the Neo Geo so I thought it would be cool if the intro cutscene had a letter written in traditional Japanese style (writing top to bottom, right to left.) The NEOGEO has a built-in Japanese font that makes this pretty easy. konnichiwa_sekai.PNG The source code for...

Re: Lesson P25 - Hardware Sprites on the NeoGeo

I added just one line of code to your SetSprite routine to enable animations. SetSprite: movem.l d0-d7,-(sp) ;d0 = hdwr sprite number ;d1 = x pos ;d2 = y pos ;d3 = pattern number ;d4 = palette. ;d5 = animation type (#$00 = no anim, #$08 or #$0C = 8 frames, #$04 = 4 frames. All animation frames must ...

Shrinking Sprites - Out of Sync

I understand that chained sprites cannot use the vertical shrink factor for scaling, only the anchor sprite can. With that in mind I have the following code and it's functional (I cut out everything that isn't responsible for this bug): pushall ;this macro pushes all regs except a7 onto the stack su...

Joypad Code Executed At Startup?

I was fiddling with the Joystick test rom for Neo Geo and ran into this problem, but I seem to recall something similar happening to me on Commodore 64 and Gameboy Advance so I'm not sure which board this belongs in but anyway... The Joypad routine doesn't check the buttons on Neo Geo (I believe it ...

Missing Files?

There seems to be a few things missing from the dev kit.
