ALL RenPy 8.x games can be recompiled using RenPy 7.x to support win32 if the game source files are available.
I do it with many RenPy 8.x games. Only games without source or packed with .RPA cause problems.
Simple games can be, sure. But not games that utilize Python 3 (without rewriting the code). And most devs aren't going to spend the time to package up their game twice for the few users still on ancient technology.
Probably you did NOT understand what I have written?
When I say I DO IT then I don't throw such words at the wind.
Sure, some games needs some more code adjustment to run on WinXP since it was dropped earlier and require older version of RenPy, but ALL games can be compiled without code change at least for Windows 7 x86 edition.
For THIS game in particular I tried WinXP version, but there were unsupported audio volume errors, so I compiled it without code change for x86 Win7 and Linux. It took 2 hours, but most of it was time needed to upload:

This is the PROOF that you are WRONG
Right now RenPy 7.x and 8.x are developed concurrently and both are nearly the same.
x86 is not ancient, just different CPU instruction set. While AMDx64 mode allows (AND USES about 1.2x average) more RAM, it's also castrated from ability to run 16-bit software, which run fine in x86 mode of CPU, though 32-bit software run in most cases the same on both.
RAM above 4 GB Microsoft reserved and allowed only for Windows Server 32-bit editions - up to 128 GB RAM with latest revision.
Mind that there are also actively developed platforms that doesn't require huge amount of RAM and are cheaper, because not require AMD license.
