WIP r830 Discuss (do not post builds)

Sega Rally 2 issues with r778 and above.

Revision 777 works fine, but there are sprite issues with 778 and above. Whenever there are people on the sides of the road there is slowdown and garbage textures...the people get mixed in with the game 3d graphics and the graphics become garbled until you get past crowds. I'm not sure what causes this.

Ian posted a solution literally on this very same page. Did it not work?

No. I have tried many different PowerPC settings to no avail.

I just tried it at 100 MHz and it works fine. Give it a try. If it doesn't work, post the contents of your error.log file.

The game is actually quite heavy on the CPU. Not quite sure why the timing changes I've made seem to make this problem worse but they do.
Logging the writes to the GPU, it takes like up to 30-40% of the frame time to send the data from the CPU to the GPU. Whats happening is the writes overlap the next frame. The HW needs to wait until 0x88 or the tilegen write happens before rendering a frame. But currently we don't so the HW will render an incomplete frame. If we implement this functionality it will fix the corruption, and the game will drop to 30fps which is the expected outcome for such a low CPU clock speed.

Sega rally is a step 2.0? game so the actual cpu clock speed should be like 166mhz. But 80-100mhz should be about fine for it.

Okay, this game is a real downer...the graphics corruption is gone when I play above 70 and below 100 but the game runs uber slow. Running this game on 777 runs perfect so what i'll do is just play this game on 777.

What happened to the rays of the sun in the first track, they are, but somehow they shine not so) in r778 when turning to the left, the rays of the sun are perfectly visible and possibly correct?

Will this bug be removed in the future)?

[Ian]

The 2nd one is a bug in the tilegen. Will have a go at fixing it. The situation was improved with the timing changes I made.

I just noticed this on the first post - what is ArcadeUI 0.217? I just haven't come across it before?

It's a Emulator from Mame but without using the consoles and other stuff is in the official mame, so the emulator is able to extract the name roms and i load it up on crlmamepro and i do this trick.
Even with mame or supermodel 3 using Emuloader it is possible to extract the name roms in a txt folder and load up in the tool to provide the dat info.
I send you a pm.
Have fun.

Olá amigo!

Just to let you know that me and Conversus were working on an audio fix to the SCSP board. It may sound cool, but it fixed Scud Race's attract music.
