[Feature Request] Per-game WHDLoad.prefs #572

Closed redmist77 closed 1 year ago

redmist77 commented 1 year ago

It's it possible to add a custom WHDLoad.prefs for a particular game? If not, it would be a useful feature. e.g. some games like Elfmania require NoWriteCache to be disabled to avoid screen flickering.

You mean on the coins of Elfmania ? 'Memory Cycle Exact' cleared that up for me.

redmist77 commented 1 year ago

No, the flashing on the loading/title/character-selection screens. 'Memory Cycle Exact' doesn't fix that. The only fix is to enable WHDLoad disk write cache.

redmist77 commented 1 year ago

Ah, it looks like this issue is handled in WHDLoad 18.7. PUAE currently uses 18.6

Details here -: http://www.mantis.whdload.de/view.php?id=5263

With this fix, it would be possible to create saves\WHDSaves\custom_Elfmania.slave containing a command "WriteCache" which would override the "NoWriteCache" in the global WHDLoad.prefs

A workaround is to remove NoWriteCache globally and then create a custom_[game].slave for every other game which contains "NoWriteCache". 😲

EDIT: A better solution would be to just replace the version of WHDLoad in /saves/PUAE/WHDLoad/C with a newer version that supports "WriteCache" to override the global "NoWriteCache"

It sure would be nice to be able to have write cache enabled always AND not lose saves when quitting RA instead of WHDLoad.
