At first I though this was a bug but it was just my stupidity.
You know how MoonShell 2.10 has its own softreset that you have to set up for AKAIO by copying the akmenu4.nds, renaming it to RPGS.nds, and copying to SD:/moonshl2/resemse? Well if you're like me you just copy over the system files whenever there's a new firmware. I completely forgot that RPGS.nds was from the previous release, AKAIO 1.5.1. I ran Moonshell 2.10 and softreseted; when I got back to AKAIO main menu and went under System Options, the Homebrew Softreset option disappeared because it never existed in AKAIO 1.5.1.
Basically what I'm saying is take the new akmenu4.nds, rename it, and overwrite the old RPGS.nds in the appropriate location to avoid this problem.
Awesome release AKAIO Team, love the homebrew softreset works wonders.
