I bought RCT1D through steam last year, and now my original copy doesn't work anymore. I had drexler patch and train patch (both by Joseph Drexler) installed on that one. Now the drexler patch is still available (but doesn't work on deluxe) but I can't find the train patch anywhere (it allowed 12 trains of full length on any coaster). The original site (strategyplanet) doesn't exist anymore so I hope someone downloaded it from there before the site was gone early this year. I want to try it on the deluxe version as it is essential for making larger multi-station coasters and it can increase capacity on some 'normal' coasters.
TL;DR: Do you have the TrainPatch anywhere on your computer? I want it.
