Yep, that is exactly what a savestate is for; I don't find the menus get in the way much, but some games take forever to load.. such as Dungeon Master (slow decompress) or Civilization (multiple floppies). So for these, just load them and drop a savestate out. Some folks even delete the original floppy disk and just keep the savestates around.. depends how the game needs the floppy later if at all.
(ie: Original ST's were 512k, while I think most were the later 1MB model. Likewise, original STs had single sided floppy, but most later models had the double sided 720k floppy drive. I think the STF and STFM were the most popular models.)
With regard to screenshots..
It could be possible to take a snapshot of the screen and include it in a savestate (say), to make previewing possible... *Shrug*
As to a fancy thumb-nail based loader.. consider.. Take the best 500 games (say).. first, someone would have to determine wat they are then collect them all and make all the screenshots. (Feel free
A decent thumbnail would have to at leats be 100x75 pixels if not more, biggest say 160x100 (1/2 scale).
I happen to have some screenshots of on of m desktop apps that is 119x66 and its a 2.3k jpg. I have some ones around 15x150 that are about 4k.
Not too big, but lets say.. 500*4k = not so bad 2000k or 2MB for a snapshot pack plus wrapper details. 2MB isn't too bad to toss away I guess, but I imagine it'd be larger, but even 3-5MB isn't so bad perhaps.
The next question becomes how to display them; given a game disk, you look it up in the games database included by crc and you get a match showing 4 games on the disk; do you shoudl them all? cycle through them? Further, the quesitn is given "Time lords v2.0" and "Time Bandits (2.1)" how do you know which screenshot to show.. we'd have to have some mapping between game names and the images. So someone would need to make that.
(This is all blue sky off the top of my head
So could be doable, but lotts of work. I am perhaps game if others are, to do all the tedious work
