You may have noticed the forum is down. This appears to be a problem with the hosting company after an update. I have run a full back now and we are working on it .... ... And it's all ok again. Happy Friday!...

The forum is really the place to see regular updates, but I thought it was time for a summary here. The Amiga code is pretty stable. Work is being done to add RTG interlaced modes and increase CPU performance further, but the main focus at the moment is on hardware. I've been working with some new suppliers and assemblers, using my Namco...

I've released a new version of the Amiga core (). New features : 48M XRAM mapped as Chip and all chipset DMA pointers support 64M addressing (optionally enabled in OSD / .ini file) CPU cache stable - 2 way I + D with full snoop. ~16000 AIBB Dhrystones Filtered & Mono audio RTG over analog/DVI/HDMI with hardware sprites and dedicated blitter engine.  1024x768 at 16...

A lot of work has been done both on the CPU to increase compatibility, and the core to get the cache working and timing closure. The design is completely constrained and this results in a very stable platform Latest features: 2K Instruction plus 2K Data cache with full chipset snoop on both.Performance is around 11.3 mips / 10800 dhrystones with sysinfo 4.0. The RTG...

Taking a quick break from the Amiga core development to ship some hardware. Workbench is full, this is the overflow storage! (These are all going to the distributors. If you were on the original list please email me. I also have boards at reduced cost for developers still)...

The latest Amiga AGA core is in beta with support for P96 compatible RTG. It also includes a hardware blitter engine which is used by the card driver to speed up window movements. There is still work to do increasing the pixel clock, but it's nice to see these modes working cleanly over DVI/HDMI. Thanks especially to Jim Drew for work...

Time for another update. Sometimes it seems things go a bit quiet here - while it's true September is a busy month with my other (money earning) activities, there has been a lot going on with Replay. I've just finished the tweaks for the DDR controller needed for the vector games (Asteroids and StarWars) and the RTG graphics mode for the...

The AGA core is pretty stable now, but one issue which has been haunting me for ages is some blitter operations go wrong and leave garbage on the screen. I've been working with Jim Drew, who pointed me at some source code released by DMA designs for Menace - Amiga Format issue 8 or 9 I think :  This was a fairly...
