Let me apologise firstly for the delay in getting this update published. It was noticed that if you ran a full race distance, some cars would retire near the end of the race because they would run out of fuel. A big thanks to Francis Zenas for fixing the magic data on all tracks. He did these quite a while ago, and it's taken me a long time to compile this updated fix.
Unfortunately, there still remains a bug on some tracks where cars get stuck in their pitboxes.
Thanks to gp4wonder & carl_gpgames for sharing DSOAL's EAX tweak. This also comes with DX8 to DX9 converter by crosire. These tweaks not only enable 3D EAX effects, but also provide much better sound quality from the samples. They also allow GP4 to run more stably and you can ask GP4 to run all CPU cores without crashing. For some machines, this will improve your GP4 performance.
