General Discussion / Retrode on Acer Revo RL70
« on: 28/Aug/2012 03:04:33 PM »
I was hoping that the Raspberry Pi would be powerful enough to run the game emulators I was interested in, but that looks to not be the case. So I set about looking for an alternative system: I found the Acer Revo RL70 nettop PC.

It has 4GB RAM, 6xUSB, WLAN, LAN, HDMI, VGA, SPDIF, memory card reader, headphone & mic sockets. Wireless keyboard and mouse, too.
It runs an AMD dual core E-450 processor, at 1.65GHz, with AMD Radeon HD 6320 graphics.

And it can be mounted on the back of a TV  8)

I have it setup using Windows XP and a bunch of emulators under the Maximus Arcade frontend. MAME, MD, SNES, Amiga.
I also have OpenElec installed for XBMC as a media player.

Works a treat with my Retrode. :)

I'm happy to answer questions if anybody wants to do the same thing.


General Discussion / Nice little joystick tester for Mac OS X
« on: 24/May/2012 07:08:25 PM »

Mac App Store $0.99/£0.69

Works well with the Retrode in my testing.

Here is a "How to" guide for updating Retrode Firmware on OS X.

I had to compile dfu-programmer myself, but am supplying a download here to make this easier for others.

Hopefully this is useful for other Mac users.



Please read this first!

Requirements for OS X:
1. libusb library
2. dfu-programmer binary

libusb installer: (make sure to select the correct one for your version of OS X)
dfu-programmer: (version 0.5.2, compiled by myself)

New easier instructions are in this post:,53.msg659.html#msg659

1. Run the libusb installer, confirm success
2. Unzip dfu-programmer to same directory as your firmware.hex
3. Backup your retrode.cfg
4. Put your Retrode in firmware update mode: hold down the upper button (HWB), press and release the lower button (RESET), let go of the upper button (HWB).
5. Check in System Information app, USB section for "Application Specific Device", vendor ID 0x03eb  (Atmel Corporation)
6. Open Terminal and issue the following series of commands...

1. change to path of firmware and dfu-programmer
Code: [Select]
$ cd /firmware/path/
$ ls
Expected results should be similar to:
Retrode2-v0.17d.hex   dfu-programmer      readme.txt

2. confirm retrode is connected in firmware update mode
Code: [Select]
$ ./dfu-programmer at90usb646 get product-revisionExpected results should be similar to:
Product Revision: 0x82 (130)

3. erase firmware on retrode
Code: [Select]
$ ./dfu-programmer at90usb646 eraseThis should return to the prompt with no output in a few seconds

4. flash new firmware
Code: [Select]
$ ./dfu-programmer at90usb646 flash firmware.hexExpected results should be similar to:
38642 bytes used (67.39%)

Finishing up:
1. Press the lower button (RESET)
2. The Retrode drive should appear on the Desktop
3. Confirm the new firmware by checking the version number in retrode.cfg
4. Enjoy the new firmware features!

Support / USB disconnect when moving Retrode - resolved
« on: 27/Feb/2012 12:17:17 PM »
Does anybody else find that when moving the Retrode when connected to a computer the signal can be interrupted causes the device to unmount or disconnect and then reconnect?

Am I putting stress on the connector and or circuit board when moving the Retrode with a cable plugged in?

As far as I can see this is an issue with the connection at the Mini-B USB connector end. So I was thinking that perhaps in future versions use of a larger USB connector (Standard-B type?) might avoid this sort of issue?

Thoughts appreciated.


Support / PS3 USB enumeration - resolved
« on: 27/Feb/2012 12:11:59 PM »

I read on the following blog post that "the usb#->ps3 controller # mapping can be changed in the menu as well"

Can anybody let me know exactly how I do that. I have only changed the number on regular PS3 controllers using the PS/home button and menu. How do I do this for USB controllers?


I use VMware Fusion on my Mac to run Windows and Linux software. When I plug a USB device in, VMware asks whether or not I want to connect it to the VM or the host - OS X. This works for a variety of mice, memory card readers, phones, portable navigation devices, etc.

However, as you may have guessed by now, it does not work for Retrode. When I plug in my Retrode it connects to OS X without asking me.

I was wondering why that might be? Is the Retrode firmware not doing something it should? Or is VMware Fusion at fault?

Any thoughts or help appreciated.


Support / Order confirmation and shipping notice? - resolved
« on: 18/Feb/2012 05:47:37 PM »

I placed a order on 16th February, paying by PayPal immediately as part of the checkout process.

Should I expect a confirmation of my order other than the PayPal receipt?

And will there be a shipping notification?


General Discussion / Retrode 2?
« on: 16/Feb/2012 06:51:58 PM »
I've read about the Retrode 2.

Am I correct in assuming that's the one currently available on the store?



I'm interested in using the Retrode as it comes, but also as a controller adapter for Atari-standard joysticks so that I can play Amiga and Atari ST games with the controllers they should be.

Do Atari-standard controllers work on the Retrode?
