I'm not as up to speed as you probably are.
Is this like, a file that can be downloaded? If so, can you point me, please?
And once that is installed...some stuff that used to not work on FBA will? I'm just a little confused.
You can find all the files needed for swap in the minimal local pack at dl.openhandhelds.org
Once you have placed all the files in your SD card, to activate swap simply (under Dingux obviously) go to settings and run at first mkswap and then swapon. Now your Dingoo have virtually 64M RAM and you can play more games in FBA (Dodonpachi, Guwange, The Great 1000 Miles 1 & 2 and others), in MAME4ALL (In the Hunt, Hook, Undercover Cops and others) and in OpenBor (Nightslashers X and Golden Axe Myth). Swap is also useful for SiENcE's GemRB and for some homebrew games like Zelda:Return of the Hylian.
