;--- Sample RAM implementation of a MSX-UNAPI specification
; By Konami Man, 1-2010
;
; This code implements a sample mathematical specification, "SIMPLE_MATH"
; .db
; which has just two functions:
; Function 1: Returns HL = L + E
; Function 2: Returns HL = L * E
; The code installs on a mapped RAM segment.
; The RAM helper must have been previously installed.
;
; To create your own implementation:
; 1) In the "Constants" section, modify the API version and implementation version
; constants, as well as MAX_FN and MAX_IMPFN.
; 2) In the "Functions code" section, leave FN_INFO unmodified,
; and add your own functions.
; 3) Add an entry for each function in the "Functions addresses table" section.
; 4) In the "Data" section, modify the specification identifier
; and the implementation identifier.
;
; Optional improvements (up to you):
; - Install a RAM helper if none is detected.
; - Let the user choose the install segment in DOS 1.
; - Add code for uninstallation.
