2.1 When simulating with MS-DOS file

This chapter explains the operation procedure of “Direct DOS File Access”.

[Procedure 0]

If a file with the project name as the body and the extension "DSK" exists, delete that file.
If this file exists, "Direct DOS file access" will not work. This file was generated when the “Real-time emulation” in the next section was performed previously.

[Example 0] C: \> DEL △ TSTGAME.DSK [ENTER]

Determine the project name.
Used as the body part of the file name of an MS-DOS file. Please match the MS-DOS file conventions.

[Example 1] TSTGAME

In this chapter, “TSTGAME” is used.

Create a script file.
Create it using a suitable text editor while referring to Chapter 3. The file name of the script file should be the project name with the extension “SCR”.

[Example 2] TSTGAME.SCR

Create a startup file (parameter file) for the preprocessing program (VCDPRE.EXE).
Use an appropriate text editor to create a startup file.

 [Example 3] An example of a startup file is shown below.
C: \>   TYPE △ TSTGAME.PRM [ENTER]  
SCR △ TSTGAME.SCR [ENTER]
RTI △ TSTGAME.RTI [ENTER] 
 

Start the pre-processing program (VCDPRE.EXE).
By entering the command as shown in the example, the preprocessing program (VCDPRE.EXE) is started and the files required for emulation are created.

[Example 4] C: \> VCDPRE △ TSTGAME.PRM [ENTER]
[Result 4]
specified in the startup file CD configuration information file: TSTGAME.RTI
Will be generated.

English environment.

C: \> CHEV △ US [ENTER]

 [Result 5] If you are in Japanese mode, the screen will flash and you will be prompted at the top of the screen.
