I made a program to replace devpac8x
If you ever go to the learn TI-83+ assembly in 28 days tutorial, you will find the tools they use to compile programs—TASM, which works on modern windows, and a linker called devpac8x, which, being a 16-bit program, does not work on modern versions of windows. Having to use DOSBOX (a DOS emulator) got tiring quite fast, so I made a replacement that I have called 84link. You can find the source at my github account named bobxonar, under the 84link repository.
