The swing..


What the customer really wanted.


Making the screw guide via CNC.


Screw Guide 1


Screw Guide 2


Guide * 10


Soldering.. Can't do SMT.... I don't have enough money...


Battery Connector soldering.


Battery connector assembled.


Battery assembled.


Cartridge Assembled


AV/S/Keyboard Connector


AV Connector Connected


Earjack.


Micro SD Connector and hidden feature (LED Flash lamp) ;(


Volume control


Knightmare Playing.


As installed at the user's site.


The real one. Logo changed.

I tried to make the 6 button controller into this, but it is very complicated to make.
I need to add Arduino or some other IC into the controller board to emulate 6 button controller...
Need to make some hole for buttons also.

I used USB 3.0 port on the right side because it has extra pins to use.
It is not compatible with USB 3.0 but I can connect USB Keyboard directly.
When I need to use S-video, I can use external AV connector with USB port also.
That's why I used USB 3.0 connector. :)

Some of the guys told me it should support sofarun but I think it is one of the software cause
anybody can use it somebody who wants. However, MSXBOY is not 100% compatible with sofarun
because it does not have extra buttons. (Select button: System Reset, Start button: Battery check/Lamp)

MSX Boy does not have any dip switch. However, it is compatible with KDL's firmware.
I draw the schematic and circuit with some dip switch enabled and others are not internally.
SD memory enabled / AV output enabled / 2048 kb ram .. When new version of KDL's firmware
comes, you could download it via pldload.com without any changes.

I used Gameboy slot but it does not have enough pins to use.
Cause I removed some pins like CS2, CS12, RFSH, WAIT, INT, M1, BUSDIR, IORQ, MERQ....
Cause it cannot supports some of cartridges even if I make external cartridge slot.
MSX cartridge has 50 pins but Gameboy has just 32 pins... I had no choice..

It was very long time to make... My back and arm hurts....
Anyways it is done right now...

Awesome!!!
Have you considered using with some serial memory in the cartridge and run a bootloader, for instance J2C ?

No I haven't. I could make serial memory -> real cart converter or something but I have no idea why
I need to make it.
