| What I miss from the 64 era is the SID chip, to be able to listen to my favorites tunes. Even if I like Paula I still miss the 6581/8580´sounds. So is it possible to include them in the V4? I suppose that the 6510 should be done in software. The ZX Spectrum Next did it and I think that the Vampire should too. It’s not a priority but it would be awesome.

| It's possible but if you miss the SID's sound why don't you get a Mister to play with? I think the purpose of the vampire is to bring the Amiga up to date with modern standard. Pamela seems to have a high sound quality and can emulate the SID with the appropriate filters. But if you want the original buggy 6581 sound ... you have to get a real SID.

I used to enjoy Sid sounds to clive sinclairs zx/ql beeper, but From the days I ve heard a500 Paula Never wanted it back. Now with Pamela (16 bit sounds) even less. There Are great cbm emulators, but if I would be a SID lover, would go for c65 replica project. V4 space Has better use for e.g. warp3d 3d Basic chip

| why dont you get the ultimate64 (c64 fpga) , it can take up to two sid chips, its even better than the sid implementation on Mister

| Because I wanted the SID in the Amiga in the first place. 3D come on...it took at least a Dreamcast to have good enough 3D games is the Vampire going to be better? if not then no 3D for me and today standard is raytracing... It is better to have the best 2D computers than adding just good enough 3D but I'd love to be proven wrong.

| SID does NOT belong to Amiga era :) Yes, I would love to run that Warp3D software. Maybe even some basic OpenGL. It does not need to be 1Ghz Chip with 1GB VRAM. Something better then Voodo 2 and Parmedia 2 would be nice. Implementing SID, dual SID etc. would be a waste. C65 did it best. Sound: Dual soft-SIDs + dual 8-bit DACs of C65 is 8-bit to 16-bit high end. Use emulation on your x86/AMD64 I never tried Hi65 but you could. AmigaOS version is a joke. EXTERNAL LINK Collection and player EXTERNAL LINK Synth EXTERNAL LINK etc. and satisfy your SID sound thirst. On AmigaOS we can try: DeliSID EXTERNAL LINK PlaySID 3 EXTERNAL LINK Tiny Player EXTERNAL LINK If its hardware,not just the sound: Some versions of Catweasel can take real SID chip. Some AmigaOS and PC software can use it. Explore that option.

| No 3D.

| Eh, Real 3D using CPU :) Or, Impulse Imagine. Ok, 3D was never Amigas tradition. Amiga 3D rendering software with speed up with RAM and CPU advancement. Maybe someone compile something for 080-MMX there one day. Warp3D m68k software and games is not a huge library, but any old days 3D would help backporting even from consoles or Win/Linux software. Instead of SID or 3D, maybe a m68k MMU compatibility layer? Its not just Amiga Enforcer fans cry it can be used for e.g. Linux m68k, MacOS Classic and Atari added compatibility? All my other desires, you have already included :)

| Or there is that old Sid4Amiga I put together years ago. No idea if it works on the Vampire - haven't tried yet, but there is an 68K version in the archive as I recall. EXTERNAL LINK :)

| Software players work well but they do not have filtering problems ... I think Kamelito missed the random noise and the strong distortion of the 6581. You can see the effort done to reproduce the logic of the sid in the fpgasid project (http://www.fpgasid.de/project-definition) Despite all those efforts according to this test EXTERNAL LINK in some cases there is a real difference in the analog output signal. You can get something closer to the original sound using a vaccum tube amplifier. Even if we have good memories of the C64, the vampire project have no time to waste with old technologies. There is still so much to do to improve the audio playback.

| 2 answers 1) yes the SID was cool. And Yes I did once do a VHDL of the SID. and Yes such VHDL could easily be added to Vamp. 2) 68080 has so much CPU power that doing the SID in Software is peanuts for it

| Yes, it's peanuts for envelop generation but it's not the same when it comes to applying a convolution filter. We need a lot of power for modern audio purpose. The AMMX provide the padd, pmula instructions for a fastfix implementation but is there a floating point equivalent instruction? Another question I ask myself, is there any documentation of the new registers added for Pamela? I think it must look a lot like the original registers between A0 and E0.
