Surf Planet (Version 4.1)

0.79u2 [Aaron Giles]


- 0.105u3: Changed user4/5 roms to gfx1/2.

- 0.80: Aaron Giles made various Gaelco3D improvements, so Radikal Bikers and Surf Planet are fully playable now. Changed 68000 CPU1 clock speed to 15MHz, TMS32031 CPU2 to 60MHz and added 3x DMA-driven_DAC sound.

- 2nd March 2004: Aaron Giles - After getting Radikal Bikers working well, I decided to figure out what was up with Surf Planet. Turns out they were relying on unspecified behavior of the TMS32031 by placing a CALL statement at the end of a repeat block. They tell you several times in the docs for the CPU never to do this, but hey, I guess if it works more power to them. With that fixed and some rendering tweaks, I'm currently getting about 30-50% of full speed on my 3GHz machine. If I turn off bilinear filtering and run at half resolution, both games are playable near 100%. Of course, I don't have the sound working yet, and that will kill the speed nicely (it's a DCS-like ADSP chip, sorry!).

- 24th February 2004: Aaron Giles - Fixed a subtle bug in the TMS32031 core that was causing problems with Radikal Bikers. Now at least all the geometry shows up okay. I'm still at a loss to explain alpha blending, Z buffering, or perspective correction. The incomplete driver should be in u2, so if you know some 3D math, feel free to have a look and see if you can't help me figure it out!

- 2nd September 2003: Guru - Surf Planet (Gaelco 1997) arrived from Pelle.
