I also have the original CycloDS Evolution, not the i version of it. I haven't updated the NTR Launcher in a long time (I have version 1.9.4 standard installed) and it's working fine.
Anyway, I decided to do some testing for you. I installed the latest version of the NTR Launcher (1.9.9) and cleared my previous settings in the /nds/ntr_launcher.ini file and just like for you, my card didn't boot. However, I remembered that when I first installed NTR Launcher, the RESETSLOT1 option needed to be set to 1. Setting that option to 1 again fixed the problem, however it needs to be done under the NTRLAUNCHER_ALT setting. So your ntr_launcher.ini file must look like this (along with any other setting you may have):
Code:
[NTRLAUNCHER_ALT]
RESETSLOT1 = 1
That is definitely what is causing the issue, because switching that to a 0 (and having no other setting present in the file) will cause it to fail to boot again.
If for whatever reason that doesn't work for you, download the archived version 1.9.4 (standard, not alt; which is what I had prior to testing) and try it out with my /nds/ntr_launcher.ini file:
Code:
[NTRLAUNCHER]
DISABLEANIMATION = 0
NTRCLOCK = 1
ENABLESD = 0
RESETSLOT1 = 1
[NTRLAUNCHER_ALT]
DISABLEANIMATION = 0
NTRCLOCK = 1
ENABLESD = 0
TWLMODE = 0
RESETSLOT1 = 1
