Thanks to Mark Tilden www.robosapien.tk for these great hints.

WORK IN PROGRESS, not useful [or at least no significant difference detected]

$95,$96 - Program main again (like $90)
$99 - like $98
$9B - like $90 ?
$9C - do nothing
$9D,9E,9F - like $90 ?
$B5 - like $97 ?
$B6 - like $90 ?
others - looks like these repeat as well (eg: record/execute one of the program areas) or do nothing


$E0 - $EE (looks like the $A0 range)
$EF - nothing
$F0 - like $97
$F1 - like $98
$F2 - Execute right program
$F3 - Execute left program
$F4 - Execute sonic program
$F5 - like $F0/97 ?
$F7 - like $F0/97 ?
$F8,F9,FA - like $F1/98 ?
$FD,FE,FF - program main again (like $90)
