dwhyte Posted May 15, 2009 Share Posted May 15, 2009 (edited) I also noticed that after assembling the slide.asm file, it doesn't work the same as the one included with the hd slide atr... I'll be disassembling the working one tomorrow to see how it ticks and adjusting it to my purposes accordingly...

AtariNerd Posted May 15, 2009 Share Posted May 15, 2009 As an aside, playing around with converting 24 bit images, it's amazing how well they stand up in 256 colors, if you use Floyd-Steinberg dithering. It's actually hard to distinguish at a 1:1 ratio on my smallish pc monitor, only breaking down if I zoom in considerably. Quote Link to comment Share on other sites More sharing options...
candle Posted May 15, 2009 Author Share Posted May 15, 2009 dwhyte: the one included in zip file is for core 1.09, so palette changes won't work at all there should be atari++ emulator ready to download within few days - work is done, just needs to be planted in web space...

You can receive even better results using Photoshop and converting to an indexed .bmp using a "Local (Perceptual)" palette... Quote Link to comment Share on other sites More sharing options...

carmel_andrews Posted May 18, 2009 Share Posted May 18, 2009 (edited) heaven, your picture you posted, does that mean you have a patched version of an emulator that also emulates a vbxe/vbxe 2 If so, is that version of the emulator available of download any links....

I got hands on it to get a feeling. Quote Link to comment Share on other sites More sharing options...
carmel_andrews Posted May 18, 2009 Share Posted May 18, 2009 does that mean we are going to get a 'true colour' version of Mega galactic llamas or beyond evil, heaven i.e to take into account the colour palette of this new upgrade or are you just playing around w/some code to see what gives Quote Link to comment Share on other sites More sharing options...
Heaven/TQA Posted May 18, 2009 Share Posted May 18, 2009 first of all that I can get a feeling for it in terms of what the beast can do... but with VBXE we are running into major issues what the games industry have... with better gfx capabilities extra gfx assets needs to be done... I could simply switch to VBXE and using the sprite engine for Beyond Evil but that would limit the target group... so I am still aiming for XL/XE with the gr8 cart as extension. but with VBXE I would be again faster as I would not need to spend time for developing my own sprite engine...

carmel_andrews Posted May 18, 2009 Share Posted May 18, 2009 well, from what i've heard of the upgrade it's like having the lynx's (atari) and amiga (high end) gfx capabilities in one upgrade And it apparently has surefire sprite capability, someone already mentioned blitter capability (giving a psx example though...perhaps they both use the same blitter hardware), does it have scaling, like the lynx Shame that it won't work with an a800 you could have a kickass gauntlet game (an exact arcade replica infact) I only hope they release the patched emu, that way more people will be exposed to the upgrade and that way more people will be able to code apps/utils or gamez for the upgrade (as long as those apps/games etc work with real A8 hardware that is) Quote Link to comment Share on other sites More sharing options...
candle Posted May 18, 2009 Author Share Posted May 18, 2009 it relays only on antic presence when it comes to compatibility, and atari800 has antic chip, right? here is a patched Atari++ emulator, i've started separate thread to not get lost in postings Quote Link to comment Share on other sites More sharing options...
carmel_andrews Posted May 18, 2009 Share Posted May 18, 2009 i was under the impression that this u/g was xl/xe only, obviously i was wrong Quote Link to comment Share on other sites More sharing options...
candle Posted May 18, 2009 Author Share Posted May 18, 2009 its just the name, it relays on antic sending gtia information on gtia color bus, nothing else, so theoretically any machine equipped with antic can gain from vbxe Quote Link to comment Share on other sites More sharing options...
carmel_andrews Posted May 19, 2009 Share Posted May 19, 2009 (edited) Now that we have an emu. that mimics/emulates vbxe behavior/characteristics can you now post some apps/utils so we can test the vbxe capabilites if not at least post the memory map and/or complete list of pokes so we all can play around with the vbxe extension to atari++ also, are there any differences (hardware wise) betw. vbxe and vbxe 2 Edited May 19, 2009 by carmel_andrews Quote Link to comment Share on other sites More sharing options...
Rybags Posted May 19, 2009 Share Posted May 19, 2009 WTF? The manual for the thing is in the first post of this thread. Quote Link to comment Share on other sites More sharing options...
candle Posted May 19, 2009 Author Share Posted May 19, 2009 hardware wise: pic508 (boot loader for loading cores and core managment) was replaced by atmega48 reducing startup time from 6.5s to less than 1 second plus providing on board oscilator for freddy chip (v1.2 uses external one) HI**** (don't remember exact type) from Intersil video DAC was replaced by TH**** (again memory doesn't serve) from Texas Instruments, because its now obsolete those are minor changes that make second run of VBXE possible at all Quote Link to comment Share on other sites More sharing options...
AtariNerd Posted May 19, 2009 Share Posted May 19, 2009 (edited) it relays only on antic presence when it comes to compatibility, and atari800 has antic chip, right? Whoa...maybe i'm reading more into this than I should, but... I thought it needed either a Freddie memory management chip or a 14mhz oscillator wired up? * (Or maybe you meant that it will process the native signals, but not neccessarily harness all that the VBXE is capable of.) If it is just a matter of having an ANTIC, that changes the whole effort-level of entry. Then we could use an older socketed Atari with an easy memory expansion, etc. A lot more people might be willing to pop their machine open and modify it if they only have to solder a few wires rather than desolder chips.... *Hmmm, a future revision for compatability across the line? EDIT: Thanks, Candle. This makes me feel a little more secure. I was a little nervous about modding one of these machines, but I have a bit more confidence, now.

candle Posted May 19, 2009 Author Share Posted May 19, 2009 Today two things are on my check list making Rybags code working on VBXE, and testing the thing with Atari 800xl ntsc, without freddie chip and without 14mhz crystal 14mhz is main clock source for pixels in vbxe, but it is synced only by clock phase 2 Quote Link to comment Share on other sites More sharing options...
carmel_andrews Posted May 19, 2009 Share Posted May 19, 2009 (edited) WTF? The manual for the thing is in the first post of this thread. Firslt, if you refer to the 1st link in the first post in this thread....it only refer's to a descrption of each location it DOES NOT actually give you the meory address of that location for example COLDETECT, what memory location is this refer to COLMASK, again what memory location does this refer to there are others but i can't be bothered to go through an entire manual case in point GPRIOR refers to memory location 26fh Vcount refers to memory location D40bh, etc that's what i mean Perhaps instead of being rude and flippant in replying to my post you could have just has easily have said ' you will find what you need in the manual' instead of telling me 'what the F***' Edited May 19, 2009 by carmel_andrews Quote Link to comment Share on other sites More sharing options...

Thank you for the tip. I appreciate any help I can get. Maybe one day I can do something more useful, here, rather than keeping the seat warm. Mind, that is a season, front-row seat...
