Re: Enhanced Blitter

As I've said many times already, extra features can be added, but the blitter is really the wrong place.. It needs to steal cycles from DMA or CPU etc., if a better MMU is developed, we could have new functions for screen copy and clearing blocks of ram fast.. With some minor patches to TOS, it cou...

Enhanced Blitter

A few weeks ago I found this topic about recreating an FPGA version of the ST's blitter. I already posted some thoughts there, but obviously the project is to recreate a feature-exact FPGA replacement because blitters are now hard to find - and some people like to add them in STFs! However to speed-...

Play with a 2-buttons joystick

Here's a small mod I did this week-end to be able to play Turrican and Turrican 2 with a two-buttons joystick instead of the main button + spacebar. I had it in mind 30 years ago but never made until now :p How to: https://www.fenarinarsa.com/?p=1590 (skip to 8:15 to see a lot of secondary weapons a...

Re: BLITTER RE-CREATION THOUGHTS

I cant really comment on all that. But creating chips like the blitter is to move us towards running them faster.. along with RAM and CPU.. So there isn't any need for "tricks" in this respect to get full screen etc as it would just be possible anyway with a new chipset. I guess any other mod that ...

Re: BLITTER RE-CREATION THOUGHTS

I started to read the whole thread and it already has been suggested to add new features to the blitter - assuming the recreation process is successful, but I don't doubt it will be. Adding new features was my first thought too, one of them is to be able to select another memory source instead of th...

Re: 68000 relocator for STE/MSTE?

Cool !! I'm not sure it'll fit in an STE though? On STE the DIL socket should be upward else I guess you can't put the keyboard back on top of it. https://www.exxoshost.co.uk/forum/viewtopic.php?f=51&t=3625 The CPU is on the bottom right, near the edge of the motherboard that gives space to the joys...

68000 relocator for STE/MSTE?

I'm a bit startled to see what's possible with the TF536 on ST. I'd really like to boost my STE, or possibly even my MSTE. However before even talking compatibility, the main issue is that on those machines the 68000 is on a PLCC68 socket, not to mention than on STE it's located under the keyboard. ...
