File types self-styled for a 16-bit program. Have to study the source code to know precisely how a file type goes.

.SPR is a sprite. Likely this could be replicated into DATA statements with simple hexadecimal numbers, or like what the TheBob did. LOL.
.FNT is a font.
.SFX is a sound to be loaded into the Sound Blaster FM chip or alike hardware.
.SCR is probably a BSAVE screen image or something analogous to a BMP or PCX or something else.

Ahhhh OK. thanks.

Just arbitrary stuff then perhaps I get you. Was this BSAVE SCR a common thing? Curious about the formats will dig more with your hints.
