i was delighted to see the event roms. there where so many events i had missed and wanted to get them for myself rather then download a save. unfortunatly they don't seen to work on my r4. i looked tried to load it onto overlord 1.2 but it returns a "bhi not found!" error.
Which R4 do you have? as so many clones of it exist today. You could see if theirs a recent firmware for your card. Try looking here: https://forum.romulation.net/threads/wood-r4-the-new-firmware-99-8-compatibility-ck3.39701/ I have the R4i GOLD 3DS RTS which is $18, this works on every DS / 3DS console including the 3DS on the 11.4 firmware. The distributions roms work great from it also: http://www.nds-card.com/ProShow.asp?ProID=149 (Use PayPal if you ever purchase them that site, not your credit / debit card)
