Not for the BoingBags I contributed to, I ensure you. The stuff there was compiled/assembled from official sources. Which is also a considerably more robust approach.
i trust you, but since the sources of amiga kickstarts and system libraries are not open we are left with no alternatives as to refrain to patches to keep it legal. its been some time since i fiddled with my a4k setup and, i must say, come up with a very stable improved custom kickstart including power windows functionality, so i dont remember what patches exactly i have applied, still afair the main ones were already included in doobrey's romsplit/remus archives.
i can assure you i have properly read out the roms of my a4k to create that kickstart if you insist;). of course i would prefer all that annoying hackery was unnecessary, the code was open and there was no necessity to reinvent the wheel from the scratch, just to keep it going like in case of aros, but alas it is not the case. i dont think the fans, customers and (be it bedroom) coders are to blame for this situation. on the contrary, from my observations the community behaves sometimes even over-loyal in comparison to rather limited support it can count on from various sources and for various reasons.
