WTB: 68010 for A500

[derringer3]

In the '90 i never heard about whdload, and i have tons of games, mostly in floppies, some which can be installed in hdd. I have never problem with 68010. If i have then is about the 3.0 kickstart. But when i switched back to 1.3 these problems are gone.

The problematic games were from 80s. By 90s the 010 and later CPUs were available and game programmers mostly knew how to handle it properly (that is not to build your own supervisor stackframes, not to use move sr,dn etc)

Nonsense. You get troubles with 68010 with certain games. These games use supervisor mode directly, assuming 68000, and die horribly. There is absolutely nothing exec can do about it.

exec handles 68000-68030 without any patching, anyway.

 :lol:
The kickstart has a modified exec inside with an .. ta ta .. "enhanced privileged handler".
A trap will lead to execution of this code, it saves all pointers correct the code and jump back to where it came from.
With this kickstart I am able to use trackloader games/demos.

And ... I have no problems!

There are more games/demos having trouble with a stupid mem-expansion.
But if I use my own Kickstart .. Reset - hold both mousebuttons - and than I have only 512KB Chip / 1 Diskdrive and so on!
