I tried the new forwarder and 693. Here are my results.
Using Wiiflow 693 with v14b forwarder, Cios used: v5 hermes, D2x v9 beta 49 245-251
Took wiiflow off autoboot (older forwarder) tried devo game. Booted first time, but not second time upon direct return to wiiflow. (Tried this 15x.)
Powered off/on, booted wiiflow, launched same game successfully. powered off/on again, launched game successfully. (did this 15x also)
Powered on, booted wiiflow, launched game sucessfully. Reset wiiflow (B+Home) launched game again sucessfully. (15x)
It appears that wiiflow needs to be reset after the first devo launch (per wiiflow booting) otherwise devo fails to launch again. (possibly something wrong with the hidden channel, or the return command in wiiflow itself?)
Then extracted the forwarder dol and installed it as autoboot. Tried to launch a game and it failed twice, booted third time...it seems to load more than it fails, but it still fails. When devo does successfully launch, I can keep it going with the reset method, but devo doesn't always boot every time you power on.
