17Changing the load program code to print out 'txt' files but still run the 'bin' files. And the debugging that ensues. Printing is still kinda broken but it is fixed in the next video

Note: I have read the fasm docs more closely since this recording, imul could be used to get the file size instead of those lines in this video; for example: "imul CX, [fileSize], 512" or something similar. Also, fasm does have reserving bytes, but it is with 'rb' instead of 'db' or rw, rd, etc. Nasm does have 'resb' but fasm has 'rb' as the equivalent. This would reserve space but not initialize a value
(Update ca. 2021): There is an unofficial, maybe official, word for turning a phrase into an acronym

I plan on actually streaming more in the near future, got better webcam settings worked out and a schedule brewing for (hopefully) regular sessions.
Suggest content you would like to see live, be it programming, gaming, or otherwise, through youtube comments or by email. If twitch has a dm feature that you can slide into, that works too, but I don't know if it does or not
