Nvram clear solves it all!
I put:-
Ragnagard - slot 1
Shock troppers 2 - slot 2
Rage of the dragons - slot 3
Loading crashed first time ( on shock troppers 2)
Re-pick games loaded
Ragnagard worked after above
Shock troppers 2 does repeat crash with unibios error
Rage of the Dragons works fine after first bios error ( on boot )
Input Booted back to Ragnagard and it crashed !
Moved games:-
Shock Troppers 2 - slot 1
Rage of the Dragons - slot 2
Ragnagard - slot 3
Locked on rebooting screen
Shock Troopers ( repeat bios error )
Power of and on
B to load slot 2 ( quick boot error ) Rage of the dragons worked fine
Jump to Ragnagard ( crashed )
Tried each game in slot 1 ( no other games loaded )
Ragnagard - bios error on boot, then worked
Deleted above -
Added Shock Troppers 2 to slot 1 - ( locked up on rebooting.... )
Power off and on - jump to slot 1 crashed
Removed cart- cleared Nvram - Shocktroopers worked fine!
Added Randnagrad to slot 2 - stuck on rebooting screen
Power off and on
Both games crashed again!
Removed randargard. ( rebooting locked again...... )
Power off and on
Shock Troppers crashes again.
Power off
Removed card and cleard Nvram.
Shock Troppers 2 and Radnagard worked!
Added SvC slot 3 all perfect! ( and jumped to other slots and back )
Removed SvC for Rage of the Dragons all perfect!
the rebooting error is a strange one ( just locks up )
I've found the unibios soft reset the easy way round it
Edit:-
The rebooting error got to me so i:-
Added my games back -
Viewpoint - slot 1
ZuPapa - slot 2
Money puzzle ex - 3
Rebooted first time nice and fast, all worked great as per!
Some how the first lot of games cause an error or two, Nvram helps games work not help rebooting lockup
End of edit -
Hope this helps!
