I have too many programmers. I didn't feel like buying another programmer (USBTinyISP) to program the DFO programmer, so it could program DFO's. 

I spend all evening trying to program the Atmega48A on the DFO programmer (it has a proper ICSP port) But nothing I tried was able to communicate to the Atmega48A. I tried Arduino_as_ISP on an Arduino Nano, AVR USBasp and lastly avrdude on a Raspberry PI.  None wanted to communicate. But I was able to communicate to the Atmega8 on the AVR USBasp.

Given an Atmega48A is pin compatible with an Atmega8 (found on my AVR USBasp), I swapped microcontrollers and was able to easily program the Atmega48A installed on the AVR USBasp through AVRDUDESS, using the Arduino Nano as the ISP.  The only difference I noticed is that pin 14 (/SS) is held to pin 29 (/RESET) and not floating like on the DFO programmer.

The Atmega48A detected fine, programmed, and now CDCE9XX is able to detect the DFO programmer.

Hope this helps someone in the future.

Hi, i would like to get some help to get a og grey x68 running (brough as junk).
The computer show some sign of life: when i press the psu buttons (behind), the power led go red and when i press the power buttons the power led go green and the high reso led go red.

I connect the x68 with a vga adapter to a crt monitor who detect something but black screen, same with an upscaller (sync on something but no picture).
I just recaped all the board (not the psu and the floppy drive) and changed the cristal near the battery. The second floppy drive as the edge connector broken (the one with the floppy ribbon).

Is there something i can verify or test?

I got it working finally in 2 button mode.  I updated the 2.4g receiver to 3.02 firmware.  They don't list the dongle firmware on their website in any obvious place.  On a facebook forum somebody told me what version firmware they were using and when I saw their was a dongle firmware I look into it.  I found an old post online mentioning you can open the dongle with a torxs bit and find a micro usb port.  Now I'm running firmware 2.06 on the controller and 3.02 on the usb receiver.  Like I said I couldn't find this on the website and it probably wasn't meant to be user serviceable.  Hopefully this helps somebody one day because it drove me crazy.

Now it works fine using my 2 button dongle built without the switch.

Next week I'll try the blue retro bluetooth reciever and report back.

Looking at cz-600 schematics (i never found the schematics for the ACE) the battery is re-charged by VCC2, the +5VSB line, so it's charged even when red led is on

My ACE battery has run out of charge. I know I should consider using something else than the barrel battery, but at least it is a "recent" one (7 years old or something), that replaced the original. And I know I will have to set the SRAM settings again, fortunately I have a system disk.

My question: will the battery charge again simply by hooking the machine up to a power socket and keeping it in "soft off (red LED)" mode, or does it only charge when fully powered on (green LED)? I'm a bit hesitant keeping the machine fully powered on for a longer period of time.

Right , well so how do Gain and Offset help , do they focus the beam more?

I built this adapter this time that says it works with 8bit do m30 2.4ghz and x68000 and I have the same issue.  I tested the adapter  with the normal genesis 6 button pad and a genesis 6 button arcade stick and the mapping is slightly different but it works.  I wonder if 8bitdo changed something.  The problem I am having is the xyz buttons don't work and when I press up or down in streetfighter the character ducks or jumps and attacks from the single input.  The only difference between this and my old adapter is the following.

In street fighter 2 the genesis 6 button pad now has the correct mapping when set to normal and the arcade stick is mapped correctly when selecting normal capcom stick.  Not capcom-md.  The mappings are a little different but the dpads work correctly on both controllers.

I also tried holding the mode button on the 8bitdo pad which says it changes between 3 and 6 button mode.

As a note my bluetooth and 2.4ghz adapters are doing exactly the same thing.  I wonder if 8bitdo silently changed something.  i bought another brand bluetooth adapter on Ebay.  Should be here next week.

FYI the RAM doesn't operate at full speed in 16MHz mode, the I/O slot bus always runs at 10MHz. If you don't want slow memory past 2MB, you need a RAM expansion that goes in the slot near the CPU. These only go up to 8MB (6MB module + 2 onboard) but in practice that's fine because nothing actually needs more than this.

You need to follow my instructions as documented here: https://gamesx.com/wiki/doku.php?id=fm_towns:sdscsi

Towns OS install CD has the correct command line utility to map partitions to drive letters and save it to SRAM. The screenshot you have shows that the partition info program is able to find the partitions, but doesn't know the mapping (The ? sign). The partition info tool (what you're using) can't map partitions to drives letters and save it to SRAM - only setup.exe on the install CD can do it.

Quote from: rezb1t on November 25, 2025, 11:25:59 AMI haven't tried the Bluetooth version of the M30(Genesis controller by 8bitdo) but I use the 2.4ghz version with a simple adapter to play most games on X68000 and it works great.

Which Adapter are you using?  I just got the m30 2.4g now and I am getting no response in games.  I have I made a 6 button and 3 button adapter from the schematics online and it works with other controllers.  Are you using something special?  In 2 button games I get no response and in Streetfighter trying the capcom stick modes I get input with the wrong controls just like the Bluetooth adapter.  I know my joystick port works because it works with even the cyberstick, fm towns controllers natively, and genesis sticks with the various 2 adapters I made.

I use a cable I bought from misteraddons.com for 2 button games, but I checked the site so I could link it for you and it seems they no longer sell it..

I use this adapter for 6 button games which works and thankfully, it is still for sale:

There's also a 2 button variant of this cable but I haven't tried it. I would expect it to work, though.
