I finally managed to get Firefox 48.0.2 to work on Windows XP RTM! Notes kernelxp.dll stays in the "firefox" directories after patching, or else it will NOT work. The unofficial guide "How to get Firefox 48.0.2 / 45.9.x ESR to work on Windows XP RTM!" is now available. This guide is made by me. https://sites.google.com/view/clara-incorporated/modernization/windows-xp-rtm/firefox-48-0-2-firefox-45-9-x-esr

The unofficial guide "How to get MyPal 68 working on Windows XP SP1!" is now available. This guide is made by me. This would be useful for Althon XP/Pentium III machines running Windows XP SP1, because Supermium does NOT support processors without SSE2 yet. https://sites.google.com/view/clara-incorporated/modernization/windows-xp-sp1/firefox-based-browsers/mypal-68 @feodor2and @roytam1

Okay. Your suggestion just worked for me as well as FindNextFileA works too when I got mypal68 to work on Windows XP SP1.

I did get Mypal 68 to work on XP RTM by installing the KB921337 update (to tweak as SP2 with CSDVersion set to 200), it is startable, but like Firefox 52 and Serpent, the stability of running these modern web applications (especially the ones patched with kernelxp.dll) on Windows XP RTM can get unstable after a while as it freezes or crashes with c0000005 (Access Violation) error at address 71ad1020. Can somebody try to manage to fix instabilities in what's causing Mypal 68's stability on Windows XP RTM to shake? P.S.: I used Mypal 68 on Windows XP SP1 and no instabilities occurred

I used roytam1's kernelxp.dll to get it to work. I used 4GB of RAM for performance on all Windows XP versions.

December 25, 2026 USP 5.2 should be finished on December 25, 2026 (because it was NOT finished on January 30, 2016).

I finally managed to get Serpent/Mypal 68 to work on Windows XP SP1 (and also SP2). Notes kernelxp.dll stays in the "mypal" and "basilisk" directories after patching, or else it will NOT work. mypal68-xpsp1-code.txt serpent-xpsp1-code.txt
