2020 (CLIENT ONLY) Patching Guide (0k method)
Open the client, hook onto it using Alt + A using x32dbg

Once there, jmp Loading shader files, Trust check failed, %s: Trust check failed, then patch rbxsig

To patch rbxsig (HE TRIED GATEKEEPING THIS LOL):
In x32dbg, search --rbxsig4, and find the first result, scroll up, there should be a bunch of int3s, and a "push ebp" below it. Change this push ebp to "ret".

I'm not going to provide RCC patches, or any API responses (cope skids), but I will provide the ticket format that was used 2020L-2021E (also gatekept by 0k)
Ticket Signature 2 Format: {userId}\n{username}\n{characterAppearanceUrl}\n{jobId}\n{dateTime}
Ticket Signature 1 Format: {dateTime}\n{jobId}\n{userId}\n{userId}\n{followUserId}\n{accountAge}\nf\n{username.Length}\n{username}\n{membershipType.Length}\n{membershipType}\n{countryCode.Length}\n{countryCode}\n0\n\n{username.Length}\n{username}
Final ticket: {dateTime};{ticket2Signature};{ticketSignature};4
The rest should be common sense.
