Update 2023.04.06:
Lola1990, Lola1991 and Lola1992 carsets were add to archive. This carsets use lola 90-92 carshape. Also I reupload all other carsets because I've found a bug: there were polygons with wrong mapping at the tail. I only noticed this error when watched Gplaps 1990 season first race at Phoenix
. Now everything should be ok.
===================
I have question for everyone. All carsets have KITs to change car options that use bat files and some other additional tools. In general KITs should work under 32-bit systems but under 64-bit system there will be error when you try to run it. Ihave 32 bit machine so have no problems with this KITs. But what about you? I can remove KITs as BAT files and create folders with options files. And then you will have to manually add files to dat if you want to change anything. But this will not work for 2001 carset because there is very complex KIT.
Other option can be if someone may rewrite few new tools. Bat files uses:
1) choice.com - make possible to have choices in BAT file. But bat file can be rewritten to eliminate use of choice.com
2) PACK and UNPACK.exe - small 16-bit command tools to pack and unpack dat file. This tools don't run under 64-bit system.
3) Pkunzip.exe - only for 2001 carset, zip unpacker tool. May be replaced with similar command tools like 7-zip has.
So main problem is with PACK - UNPACK tools for dat files.
