the next time i see some soydev bragging about writing a shitty hacked up DOS mastodon "client" I will ask them if they can run it on superior japanese engineering
none of your ints are the same, you have no VGA, and the IRQs are mixed up with INTs that have different numbers that you have to look at a table to translate into IRQs. None of your "C sharp or rust to DOS" compilers work either because of this. Good luck.
