Exemple code

;Uncomment next line and...BOOM!
;USE38 = 1; to use 38h as interruption hook
;Comment next line if you uncomment line before.
USE38 = 0; to use 0FD9Fh as interruption hook

And with MEGAROM directive you can't use PAGE 0, PAGE 1 or PAGE 2. If you use it asmsx says:

code/data without subpage

PAGE 3 yes. No problem.

I got a SEGFAULT. Nice.

Maybe we can throw an error when using PSEUDO_ORG when if(megarom && addr < LIMIT_ADDR). We have to decide which is LIMIT_ADDR.

[Fubukimaru]

This also crashes (Super minimal example):

	MEGAROM	KonamiSCC
	ORG	38h
	db	0C3h

[Fubukimaru]

The code is incorrect. With MEGAROM 38h hook cannot be used.

A PRENDRE PEL CUL.
