People like you always wants the cheapest version, which is offered by scammers and wondering why you've been scammed.
I am not offering doing such jobs, but telling you that this is not a job for monkeys if he wants his WHOLE datapack to be converted into newer lua system, which could include unique mods/scripts or what ever. This will take way longer than a few days. And I am telling you no single programmer will do this on otland. Those which are good enough to do this, wont take this job. Those which are not, will fail because they will face weird issues as soon as they see some random datapack which needs to be converted, result: scammed.
You post above proofs how bad you communicate with other people you dont know about, and how less experience you have in everything you talk about.
I wont answer to any future replies to this thread.
PS:
Is there any way not having a full 0.3.7? Custom codes ripped from higher/less versions?
