MSX Memory SDCC Libraries (fR3eL Project)

Architecture	MSX
Format	C Object (SDCC .rel)
Programming language	C and Z80 assembler

---

Description

This project provides two libraries for accessing the memory of MSX systems:

• memory_Z80.rel provides you with functions to read or write to the memory.
• memory_Slots_MSX.rel allows you to configure the pages of the slots and subslots.

Use them for developing MSX applications using Small Device C Compiler (SDCC).

You can access the documentation here with How to use the library.

In the source code examples/, you can find applications for testing and learning purposes.

This project is an Open Source library. You can add part or all of this code in your libraries/engines.

These libraries are part of the MSX fR3eL Project.

Enjoy it!
