If you have a huge SD card and don't care about wasting the space it's by far in your best interest to manually decompress the ROMs. Actually, it'll be worse since you'll now have both the compressed and uncompressed files taking up space. It's something worth trying though recent versions should uncompress to file if uncompress to RAM fails, but sometimes memory failure isn't graceful or obvious and therefore it'll still just crash later.Įxophase wrote:The thing is, if the app uncompresses every ROM it'll defeat the purpose of supporting compressed ROMs in the first place since you'll no longer be saving space. Of course, the other option is to disable uncompress to storage altogether and rely on uncompressing to RAM, but Android devices are so stingy with address space this can quickly become an issue even on devices with a lot of RAM. The best compromise may be to allow a user configurable cache size, where it'll delete previously uncompressed ROMs to make room for new ones in a least recently used fashion. The thing is, if the app uncompresses every ROM it'll defeat the purpose of supporting compressed ROMs in the first place since you'll no longer be saving space. When I tested that (it was a while ago using the trial version of DraStic), it seemed that every time I chose a new game, DraStic unzipped the archive to a temp file in its directory on the SD card, deleting the previous unzipped game file.

If in future space becomes a little tight, the user can use a file manager to delete some unzipped ROMs to save space, retaining the ability to play those games in future (since DraStic would automatically unzip the game if needed). They can store their games zipped, but as they play each game the already-unzipped files will be used more and more. The use case for this would be if the user has a large-capacity SD card with plenty of free space (e.g. Don't delete any uncompressed files automatically. Automatically uncompress archives, but if the uncompressed file already exists in DraStic's directory use that directly instead of unzipping. That can take a very long time.Īpart from making loading games very slow if you switch between games a lot, that causes a lot of wear to the SD card. That should save time and reduce wear on the SD card.Īlso, I may as well use this thread to give a suggestion relating to the Enable uncompress to file option. When using zipped ROMs, have an option to only unzip the trimmed length of the ROM. Perhaps that could be an enhancement for a future version: I've not personally explored all the distribution roms we have in great detail, however that's the most unique thing found in the file system of these distributions that i'm aware of.Thanks for that. This is documented pretty well in this thread: Unreleased Pokemon Slot 2 Distribution Azure Flute / Arceus Distribution Download along with a couple of videos showing it working. However if you load the rom in Slot-2 on a NDS emulator, then then load a Japanese Pokemon Diamond or Pearl game you will find out that decchi.bin is also a prototype slot 2 distribution rom used for testing in the early days of Diamond and Pearl. This is a Japanese GBA prototype of the original Pokemon Ranger game, you can load this in a GBA emulator and it will show a title screen with a serial number. If you extract various distributions such as the Winter 2011 Celebi or GameStop Deoxys you will find a file called decchi.bin in the roms file system. You can extract a rom using NDS Header Tool.Ĭlick the "File System Info" tab then "Extract Rom Contents", like so:
