Running SaturnOrbit project on actual hardware?
- Thread starter CarlosTheMover
- Start date
After some experimentation, the problem is most likely in my code. I substituted my 0.bin with .bin files from VF2 and VF2 ran no problem. Then I found some of Rockin' B's samples that actually worked on hardware. The first samples I had tried when I first started didn't work so I assumed it affected all of them. So that's good to know.
So at least now I have a baseline of something that works and I'll compare what I have with it.

Wasted a few more CD-Rs (god I need a dev cart) but I found out that my program does actually run on the hardware. Printing text to screen works but everything else (sprites and backgrounds) is bugged.
Here's the source code to what I currently have. It also has a built .bin and .iso files.

This is my first project on Saturn, so please be gentle 🙂

yes it is 🙂
about ip.bin you just have to vérifiy if the start address of your binary is the same as inside the ip.bin
Which project(s) did you try?
Yeah, that's what I figured. Thanks!
I've sent a mail to cafe-alpha's page about a preordering dev cart. Is that the only one of that type that exists?

Is setting up a gouraud table a requirement? I'm trying to figure out why some of Rockin-B's demos work on hardware and I'm not finding a lot of differences in his approach other than that. I'll keep looking.
Actually, it's not crashing. Everything is just black. As I mentioned earlier, I can print text on screen and I can change the text every frame. I just can't see anything else. Sprites are RGB so I shouldn't be having any black palette issues with them. Backgrounds use a palette, though.

sprites are normally easy to display, bc ground can be harder (because of cycle patterns)
maybe you can do some loops to play with priorities (0 to 7) and see if something changes

If you're seeing text, then I believe at least one NBG background is set up correctly.
It could also be that you have not initialized something correctly. Could it be that you have more than the necessary backgrounds enabled? It could be that one background is covering all the rest.
What about sprite priority? Aside from sprite types, you should have PRISA and PRINA set correctly.

Sure. I'm using the SGL so I'm thinking the defaults should be okay, though.
I have one other background setup. I could also disable it and see.

Don't assume that the defaults should be okay. This could be the reason why you're seeing a black screen.

Spent the day working with cafe-alpha's dev cart. It was pretty productive! I figured out the problems for both the sprites and the backgrounds. Debugging cycles were much quicker than burning CD-Rs 🙂
(Saturn running from a video capture cable)
The sprites were bad because of an uninitialized variable keeping track of texture locations.
The backgrounds were bad because I was using A0_BANK for tiles and A1_BANK for backgrounds. Switched both to use A0. I attempted to use B0 for both but the palette was wrong. Didn't really investigate further.

So I'm quite happy that it runs now!
