Alright, I'll stop trying to cheat on Battle network 4 Red Sun. The dual column format causes a crash in GBAATM Rebirth with the experimental AR support selected and the relevant codes for codebreaker either have no effect or the opposite effect of what is desired.
I have tried the formatting with brackets around the name but to no avail. Turns out it shows every line when mistakenly set to codebreaker format, but when set to experimental AR format, nothing shows up. Sorry for influx of info, just trying to provide info so we can figure it out.
I've been attempting to use the experimental feature to use Action replay Codes on Mega man battle network 4 Red sun. Managed to get around the crashing by keeping the cheat single column, but every line of the code shows up as an entry in the trainer menu now
