  1. 2016.04.24 Z80 MSX card runs more games 2
  2. 2016.04.19 Now it can play more MSX Games
  3. 2016.04.16 Z80 card runs MSX Game
  4. 2016.04.08 Z80 card runs the MSX BASIC

I've tested more MSX game ROMs.


Alll are working with good sound.









Bosconian



Runs little slow.



A few of games are not working properly cause of Z80 CPU running slower than original MSX speed.

This Z80 CPU card runs 2.045Mhz  so, if games used a S/W loop delay, it would be a slower than Original Game speed. But, Many of games hard to feel the slowness. Maybe interrupt driven used for delay on the games. 

This is good approach and helpful even less or faster CPU system.


And now, I'm tuning it to make better.

Keep watch it How much could I approach for the MSX computer.

Thanks

I've tested below ROM file.

It works fine.

Mostly my favorite games.























I didn't test all games, just some what I liked.

Not all of games works but, many of games could run on the My Z80 card.


This card isn't for running games but, for MSX enjoy.

Hence, I will start for Keyboard emulation for MSX BASIC and other purpose.


Thanks

It start to run MSX Game as the attachment.



Having trouble to watch the video?

Please try here.

Left monitor is for MSX system, Right one is for APPLE IIe.

Now It need two monitors but, I will combine the Video signal hence only need one monitor.


I used SD DISK HDD mode to load MSX BIOS and GAME ROM data into the Z80 Board.

And easy to load ROMBIOS of MSX and Image file of GAME ROM.


The Z80 board have 512KB Internal RAM and Main BIOS RAM area shared with APPLE II main memory.

Other Memory area can remap to 1000H-4FFFH for APPLE II access.

So the results bring easy handling by APPLE II.


It also act as the Softcard. (The Last movie parts) and working properly.

This is a Joypad for MSX Game.

 


But, I'm considering if it possible to use APPLE II keyboard to Joypad emulation.

Anyway, I will keep going to complete it for me.


Thank you very much.

Z80 card run the MSX BASIC.




But, Still I have to do some more to support SLOT concept of MSX system.

And Keyboard and PSG(Sound chip).


I'm working for the SLOT memory but, It is hard to do now. cause there is no easy memory space for MSX.

Hence I decide to add one SRAM for MSX system.


It  become complex than I expected cause the SLOT memory space really required to run GAME of MSX.

And the SLOT memories having overlapped address on each SLOTs.

So, I'm having difficulties of this.


Anyway I will try to implement this SLOT for my Z80 Card and want to see the running MSX in my APPLE //e.


Thanks
