Does anyone know how to load in-development DSiWare titles onto a development 3DS? Surely Nintendo had a way to allow DSiWare to be tested on a dev 3DS...?
I mean, it would seem like some of the titles that don't use DSi-specific features are just being developed on a regular DS SDK (or DSi) then packaged into a final DSiWare format with a more restrictive TRC along the way.
The TWL (DSi) SDK generates .srl and .tad files, but those aren't what are needed for a development 3DS. Development 3DS's use .cia files. .cia files can contain DSiWare applications. I just don't know how to make dev .cia files from dev .srl/.tad files.
Have you tried 3DSGuy's make_cia with the '--srl' option? https://github.com/Tiger21820/ctr_toolkit/tree/master/make_cia You probably need to fill out the key data in ctr_keydata.h before compiling.
