Doesn't most NES/SNES games do this?

This document have been very helpful to me.

Edit: This is also good;

You have to write 2 8-bit values to each register.

I have a stock NTSC SNES, but I had to get a RGB cable to get it to work(I'm from Sweden).
Could that be your problem?

I have been looking at it a little since yesterday, thanks!
Gonna see if I can understand it all this weekend, and hopefully be able to contribute something.

Yes, mega man x.

Thanks!

I'm slowly learning SNES programming as well, and have been looking at the same tutorials as you have. Here are 2 simple programs, if you want to have a look. Written for bass v14 by byuu. The scrolling one have some dodgy clamping, but it was mostly just to see if I could scroll the screen at all. ...

EDIT: I took a look at the "tutorial" -- now I see what's going on there. Meh, I don't think all that logic is necessarily needed for what you're trying to do, meaning you don't need to do anything if someone releases a button -- all you want to know is if a button is being held and if so...

Sorry, I forgot to mention that I did fix HandleInput: to use 16-bit indexing registers and increment the camera in X. Damn, it was those < things, it works now. I did remove them at one point to see if that was it but it wouldn't work then either. Must have been something else at that point messing...

< byte, > word, ^ long(24-bit).
Like lda.b or sta.w in WLA.

I doubt that since the sprite moves around, and camera_x and camera_y is updated in RAM. It won't write to the PPU registers for some reason. Anyway, here it is: ReadJoypad: php - lda $4212 // When 4212.b0 is reset, the joypad is ready. and #$01 bne - rep #({MEM} | {XY}) ldx {joy1_raw} lda $4218 sta...

Yupp, found a way to check the registers, and it seems like they are not updated at all. This is all of the NMI: NMI: pha phx phy php sep #{MEM} stz $2102 stz $2103 stz $4300 lda #$04 sta $4301 stz $4302 stz $4303 stz $4304 lda #$20 sta $4305 lda #$02 sta $4306 lda #$01 sta $420B lda <{camera_x} sta...

Hey! I'm having trouble getting scrolling to work on the SNES. I have looked through "Walker.asm" from neviksti's SNES-starterkit, and as far as I see, you only have to update 2 variables in RAM in your moving routine and then write those coordinates to $210d and $210e in the NMI. This is ...

Great graphics and really nice font!
Didn't know about this game until now. 16.353.993.196 CpS at the moment. Thanks a lot! X_X
