Right now only AceKard 2i. I'm using Decrypt9 on 3DS to flash a custom rom to it. the rom the DSi see's is in a section of the bootloader flash that it doesn't officially support writing to, so I modified Decrypt9 for this.I may release this build of D9 if I can get a flash dump of the older hw revision of AceKard (the ones with hw id of 44). The offset for that second rom on the older carts may be different so I will not release anything that might brick the older carts.Also you need hax on your DSi because you have to downgrade it to 1.4.0 and modify the DS Cart White list before you can boot carts with modified roms. (hence how I booted it with a rom that isn't a game spoof.The firmware downgrade is because on 1.4, Nintendo forgot to check the RSA sigs of the DS Cart White list SRL. The process is not user friendly right now unfortunately so there's not yet any tools for doing this. I wouldn't recommend you attempt it without a hard-mod. I don't have a hard-mod, but it's mostly safe for me because I know what I'm doing.
