Having been netbooting longer than raspberry Pis existed, the time limit hack has been around in triforcetools the whole time, but due to instabilities in windows python or simply due to wanting to be able to shut off the PC after the NAOMI boots, I always used a key instead.
You really owe it to yourself to try WiPi, its been completely rebuilt from the ground up.
No more buggy PiForce tools backend, I've been running for over a month now without a SINGLE issue.
No more CRC checks, no more zero keys, no more LCD hats...
I turn on the arcade machine, the Naomi automatically boots Dragon's ONSCREEN menu, I select the game I want to play from said menu, it reboots to that game.
It couldn't be more simple, self contained or to be frank perfect unless a actual Naomi Everdrive comes into existence.
