c857b00035 fixed crash when debugging 8k mnetwork ROMS 
GetBank() implemention for mnetwork reported bank 7 as being the bank
ocuppying segment 1 (the second segment). this is fine in most instances
except that in 8k mnetwork ROMs there is no bank 7. the correct value
for segment 1 is the number of the last bank number available in the
ROM, which in the case of 8k ROMs is bank 3

8k mnetwork ROMs are not common. I only know of Bump'n'Jump

67dbd134cb ACE startup copies GPIO registers to "virtual arguments" area 
this is new for the ACE-UF00 version of the ACE format but seems to be
backwards compatiable with earlier versions (the reference PlusCart
implementation does not dinstinguish between versions when preperating
the virtual arguments)

e8e5daf011 better control of timeline thumbnail generation 
previously, throttling of thumbnail generation was controlled by the
clock. for fast running emulation this wasn't a problem but for slower
emulation (eg. ACE) this was ineffective and caused multiple thumbnail
request to queue up

this revealed a general inefficiency, even if it wasn't noticeable in
"normal" circumstances

the new throttling method prevents more a thumbnail request to be
generated if one is in process
