Sorry if I didn't reply, but I have some stuff to report.
Since rxTools is pretty hardcoded and I have no knowledge to make a proper modification to fix the outdated code and the lack of a9lh support I decided to make something diferent.
I talked with
@Wolfvak on discord and he recommended me to better make rxtools from stratch, so I finally decided to make it what users are actually demanding, a CFW that feels like rxTools but isn't rxTools at all.
I present to you Lima3DS!!!
This is a pseudo-clone of rxTools that feactures tools that are taked from D9 and E9, the CFW will be totally based on Luma3DS because is the most up-to-date CFW out there and will feature a DevMode based freeway because Luma lacks of a minipasta-like mode, I doesn't feature any new atm since its only intention is to be a rxtools-like CFW/Toolkit. Atm it features a simple UI based on rxTools 2.6 and D9, but it will feature a simple version which will feature a GUI like PastaCFW with not optional patches and an advanced one which will feature a GUI like PastaCFW + the JSON GUI made by dukesrg from YARX with optional patches like Corbenik does (except for firm protection, I don't see the point to make it an optional patch). It will be compatible on every entrypoint and on any FW between 4.x and 9.2
It's still in wip and I will try to push a prerelease as soon as I can (too busy on this week and in the next one).
