For a while now there has been an intermittent problem with receiving ethernet frames: The occasional byte of a received packet is corrupted. The CRC of the received packets is checked fine, so I am assuming it is read/write contention on the receive buffer dual-port memories: Basically if you

Howdy folks,
Feral Child has been working through the European summer heat on the OpenROMs (our free and open-source C64/C65 ROM project), and has the following update for our reading and viewing pleasure:

Hi there! It's been a while since the previous Open ROMs update, time for a new one!

This week we have been testing all the changes made on the R3 PCB. The pain has been that we have a very tight time-frame for this, and I don't have one of the new R3 PCBs here with me.
In short, we have to tell Trenz in the next day or so, whether there are any known problems with the board, so

Another exciting moment this week: We have the samples of the Revision 3 PCBs for the MEGA! Pretty pictures follow, along with some discussion along the way.
First up, we can see that the PCB is quite similar to the Revision 2. In fact, it has as few changes as we could get away with, while

A couple of weeks back, the latest release of ACME added support for the MEGA65's CPU via the m65 CPU type. This provides 1st-class support for all of the 4510 opcodes, as well as the 45GS02 extended instructions. So now you can, for example, do:
LDA [zppointer],z
to read any memory address,

In short: the m65dbg tool has now integrated facilities provided by the m65 and mega65_ftp tools.
What are all these tools?
- m65dbg is a tool I wrote to enhance the remote-debugging experience for the mega65. It builds upon the serial monitor that the MEGA65 provides at the hardware-level.

The HDMI-compatible audio drama might finally be coming to an end.
Adam has kindly written an implementation that uses direct FPGA lines instead of the ADV7511 chip, which we have confirmed works on the QMTECH Wukong FPGA board.

The Wukong board is quite amazing: It is a complete 100T based FPGA -
This post is about something that I have had in mind for a long time: A couple of years ago (or possibly more), someone pointed out to me that the DMAgic controller could in theory be used to paint textures, since texture painting really is just a matter of copying a texture onto the screen.
