R13 close, honestly!
QUOTE
Apologies again for the lack of updates. I know people get nervous when I don't update regularly, but I don't like to post when I have nothing new or exciting to talk about.
I'm very close to releasing R13, I've just been struggling to find the time to add the final finishing touches to the savestate support. I've found it hard to get into a regular working pattern since moving, so what should have been a 1 week job has ended up taking a month. Bioshock and Halo 3 haven't helped either.
Savestates are working very well. The current implementation provides 10 slots which are shared across all roms. You can save to any slot at any time from an option on the Pause menu, or choose to reload a previous savestate. In this way it works just like QuickSave/QuickLoad found in various PC games (I'm tempted to add a special slot for this to the top level of the Pause menu).
I use zlib to compress the savestates, so an 8MiB savestate compresses down to 1MiB (or even smaller if you're running games which don't use the Expansion Pak).
There are just a couple of things I need to finish off now before I can release. Firstly I need to check if the savestate you're loading is for a different rom than is currently loaded. If this is the case I need to scan through your available roms looking for the correct one, and load it. To make this efficient I need to get the RomDB which I use for the PC build working on the PSP.
The second thing I need to do is come up with a decent way of linking some metadata to the savestate so I can show this in the UI. Just simple stuff like the full name of the rom, time the savestate was created and the total time spent playing when it was created. I figure without this information it'll be quite difficult to figure out what it stored in each savestate slot. The alternative is to add a text entry system to the UI so you can name each savestate, but I think this will just delay things even more.
In summary R13 is really close and I've not forgotten about it. Just a few more things to sort out and it'll be ready for release.
