Kempston interface. Mnemonically I remember this as Kemp's Town. There was some dude in England named Kemp many years ago and this was his town. Ironically we didn't hear about the Kempston interface much in the US. Sometimes joysticks sold here in the 80's had a K switch.
Bouncing Bomb Redux is a fantastic game. You need to hold down to do lower jumps, up to do higher jumps, to get around the level. I played through the whole game, it has secret levels as well.
Neat little adapter. I made the reverse of this, (sort of). I got a buld your own USB joystick PCB that I wired up to a 9 pin kempston plug. I can use my original Speccy joysticks through USB with Speccy and Amiga emulators.
The DivMMC Future also supports 3 button Kempston (I tested with PEEK and PRINT in BASIC), although I don't think I actually found any games that used it!
That port crap on C-64 where devs seemed to randomly decide which controller port to use just drove me nuts when trying to play games on emulators. Did some think many had a mouse connected for GEOS???
Hi Chris. Hope all is still good your end. My other half, Wayne, has been diagnosed with Post Combat Stress Disorder. Thereby undergoing treatment. But this is hardly the place to talk about such things, as I'm sure you will understand(?) Warmest Regards, and Respect (Wayne), Barbara and Nina ❤️❤️🕊🕊🕊🕊🕊👍👍👍👍👍👍
Not sure if it is dirt or not but the ceramic cap close to the pin that was not soldered looked to have a burnt spot in the middle. May want to take that out and test it as I suspect it failed open circuit.
The same as the Lightgun - the sensor in the light pen detects the scan line being drawn as the computer draws the screen, line by line. When it detects the beam it tells the CPU, and the CPU knows where it was up to at the point the light pen detected the beam.
Does the Mega Multi support 3 buttons in Amiga (not CD32) mode? Would be great if it could also support 3 buttons in C64 mode, however for the C64 buttons 2 and 3 go high (+5) when active, rather than to ground. When is this released and will end users be able to update firmware?
It supports 6 button in CD32 mode, which means 3 buttons should work too! 3 buttons in C64 might be there too, because when I tested Robocop 2 it used the A and C buttons, ie. B - secondary fire wasn't used in that game it seems?!?
@@GadgetUK164 I think there are a few 64 3 button games, but only hacked ones, nothing commercial supported more than the C64GS 2 button pad. I seem to remember there is a 3 button Turrican hack.
hi mate is that a issue 2 bored ? .as you get a dark pic ,it may be the comp mod you did need you to change the two transistors to brighten up the picture by the RF out put and oddly the mod requires you to put them in the opposite way around , but I bet you no the mod I am talking about < P.M. me if you have time
Anything which supports the Atari style pinout and has 5V present will work with the MegaMulti. I am aware there was an issue booting Mister with a blisster adapter connected -- I think it was being detected as a megadrive controller and not working. However if you plugged in after it was booted, it worked fine. But then again, blisster supports megadrive pads natively, so it's not really needed.
And it wont work with the MSX! That's a different pinout -- I may do a different version for the MSX. It will only work on the TFMSX as that actually uses an Atari style pinout.

Excellent to have another video of yours on this so boring saturday ;)

BTW - that "micro" wasn't an MCU but a Xilinx CPLD!

Great Video 👍
Thanks 👍

I hope Wayne is doing OK! After the last comment where you said he had died!

I noticed that too, I think it was just flux!
So, you get a product that doesn't work. You say it doesn't work and that you didn't break it. Then you get blocked, well that's nice.
Gyruss and Dropzone!
Does the light pen work on reading where the screen is drawing and then compares that to time and it knows where the gun is pointing?

Yes, it supports 3 button Amiga (non CD32), Kempston and C64 games. :)

@@RetroHQ When will these be available? I need at least 4 of these…

I think you mean the Spectrum +2? I am not aware of the 48K models needing that mod?!?
Hello mate hope your all good, be great if this worked with MiSTer FPGA.
It probably does if you can plug a Kemspton/ Atari in!
