Monster Truck Madness 64 - overlapping text tile? #138

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
The text on the game menu seems to be wrapped or overlapped by another 
one(image1-3).
On LLE, it is worst because you can't even see the text.

You can't see the text with Ziggy's plugin.
With my plugin, the bug looks the same as in Glide64.
My current theory is that the computation of TMEM addresses for 4-bit tiles 
fails. I know that the RDP:
1. uses nybbles to calculate all TMEM addresses;
2. uses a sophisticated method to round TMEM addresses off.

I have been trying to download your plugin and its source that you posted on 
emutalk but not successful.  I think I have problem downloading from easy share.
If it is not too much trouble, can you post a link on mediafire for me. Thks.

I posted the RSP plugin in 2008, but I haven't released my RDP (graphics) 
plugin, which is responsible for this effect.
Anyway, here's a screenshot from my plugin.

No problem.  I will test it when you release it.

I solved the problem, in a very logical way. The thing is, if texel1 is used in 
the 2nd cycle of the combiner, it is in fact texel0 (what Ziggy called 'texel 
swapping'), BUT for the next pixel (s + ds, t + dt), not for the current pixel.
This is more logical from the RDP pipelining point of view, than Ziggy's idea 
of texel swapping.

This problem is not corrigible under Glide3x API, is it?

I'm not sure. Did not try to fix it yet.
