Supported by CD emulation system.

These three files can be accessed simultaneously, but if there is a file with the same name,


 (1) Memory file

(3) CD file 

Reads in priority order.

Simple CD simulator does not perform real-time emulation.

■ Simple CD simulator / SIMM system

● SIMM system overview

The flow of processing during debugging is as follows.

1. Create a binary file that should be placed on the CD.
   Use
2. [MFCAT.EXE] to combine multiple files and create a memory file.
   
3. Load a memory file into RAM on the target.
   Use the
4. CD file system library to read a file from a RAM memory file on the target in the same way as reading a file from a CD.
