For the Super Nintendo, what is the best way to initiate the sPPU?

I'm trying my hardest but I can't get it to display anything nomatter what I do. What do people usually do when they make homebrew snes games?

 

On MD you first set the VDP registers, then clean up VRAM... I guess something similiar applies to SNES aswell as other machines.

 

but look at how complicated the sPPU's register set: http://en.wikibooks.org/wiki/Super_NES_Programming/SNES_Hardware_Registers

I tried several times setting all this stuff up, but it never works in the end.

 

That's a lot of regs....... well, I'm not very familiar with SNES so I cannot say anything further...

 

Check out Neviksti's starter kit: http://nesdev.parodius.com/SNES-starterkit.zip

 

... or ATX intro/menu sources by PAN & TWK. There's a few to be found online.

 

I followed the directions exactly on the snes starters kit, and it didn't even work at all.

BTW, my computer thinks my new rom is Super Mario World, just because I erased the code from a Super Mario World rom so I can write my new code over it. It says "checksum fail" and "bad rom" when I boot it up.

 

Uhh start from scratch? Dunno what else to say

 

Thanks guys, I finally have accomplished something in programming.

Now I can finally prove to people I do know how to program and I am not an idiot.

 

Time to make your own demo now

 

Soooo.....you've reversed the controls in the premade demo and then recompiled it....am I missing something here?

 

Oh wow, like anybody can create a high-budget quality game with 100 levels in less than 10 minutes.

 

EDIT: Delete.

 

Everyone has to start somewhere. Modifying someone else's example and pushing forward can help. But I do find it rather hypocritical that you were dogging on japanese Super Famicom developers for making bad code, and you couldn't figure out how to make the SNES display something on your own? I'm not trying to pick on you, but I really think you shouldn't be insulting other people's work when you then need help yourself. You came here acting like some sort of pro and now you are asking for basic help. There's nothing wrong with asking for help, but you shouldn't have acted like a big shot.


TmEE, SNES may seem to have alot of registers but it really isn't that hard to figure things out if you put some time into reading a document about it. But I'd understand if you're busy with the MD.

 

That's basically what I said but deleted. Your Math skills are supreme and godlike we get it...but don't cry about code until you can put your bolean where your mouth is.

 

I'm different from other people. The thing is, once I get all 128 sprites displayed I know for a fact they will display with no slowdown, getting them to display it the hard part.

 

Compared to MD there's 5x more of them so it is many

I don't plan on doing any SNES dev, at least not anytime soon... I have Saturn in my list after MD...
I do like to learn about "competitive" hardware though

 

That's easy to do. Anyone can plop a bunch of sprites on the screen. The trouble comes when you havea full fledged game running. In the case of Gradius III, I really don't think it was Konami at fault for the slowdown when you have 4 options rotating around you, lasers blasting, and a bunch of enemies on the screen. But I'm sure there are other games that were slow due to lazyness.

By the way, saying "I'm different" and nothing to back it up translates to saying I deserve special treatment or recognition. You won't get either without something to back it up. Good luck in doing whatever it is you are trying to do. If you just want to develop something cool for the SNES that is great and you can ask questions here and get some help. But no one here is going to worship you.

 

There, I said I can have 128 fast moving sprites with no slowdown, and I did. Next thing I'll do is to apply collision.

 

Congrats on getting the code up and running.

Now you only need object-to-map, object-to-object, scripted map system with event triggers, and don't forget to fixed point velocity for each object. Oh, and possibly enemy AI. ;-)

You are and so are the other 6.7 billion people living on this planet. Nothing good ever comes from being arrogant, but such is the way of youth and their first real taste of greater knowledge. :yatta:
