Preserving all the old C64 emulators on Amiga

[ransom1122]

Smart Refresh Disabled fixes the gfx glitch.. Now my C64 Emulated HDF is working perfectly without gfx glitches and perfect speed with A4000 68040 Quickstart and 8MB Fast

i ask cause on emulation there is a good speed increase running the emulator in Fast instead of Chip

lovely the idea to add a drive
if you know other titles that doesnt work, you can post them here

The 1200 runs faster because the Vampire 1200 V2 is roughly 4 time a 68060@50 and it has indeed maximized RAM access that no other accelerator can match so far as i believe.
You mention running from Chip RAM because you can have as much as 8 MB in WinUAE? But there is no way to have an OS running + Magic64 only in Chip RAM, such a (real) computer needs a least 10 - 12 MB Fast just to load the workbench and other stuff. Real Amiga are limited to 2 MB of Chip RAM as you surely know.

A second non working game comes to mind : Myth (i believe it is the same game that also exist on the Amiga).

Yes that same option is "raffraichissement +" in the french localisation i am using.

consider a longplay

thanks
i think some differences are also related to the fact that im launching the emulator in the most 'lite' way, without workbench or OS;
it does require 2MB to work in this way (2.5 to be precise)

also lowest standard resolution, non rtg

ill share with you some tries, now im curious about the real CPU performance

all the Amiga C64 emuls are all very buggy , nothing that can be compared to the good C64 emulators that are on PC

I tried all. A64, Magic 64, frodo etc
they are all abominable and incomplete, in my opinion they do not deserve any preservation

Magic64 Works perfect under A3000 Mode with 8MB Fast, Disabling Smart Refresh

Magic 64 is the best,that's for sure, but there are tons of games which not works there
also there are lot of glitches in some games, and the sid sound is buggy and laggy etc
and u need a 060 or fast Amiga to get a descent emulation

No C64 emualtor for Amiga will be perfect. But for Zorro Magic is

isnt this true for a lot of emulators out there, runned on different platforms than pc?

my idea is to preserve the software, possibly having the working disks, and full registered versions

i think a good bunch of .prg's and tape single loading games should perform ok with that config

the first era c64 games

Nothing beats emulating other retro computers on the Amiga, I simply don’t care doing so on a modern PC.
There are a lot of them working perfect or nice.
Mac68k
Pc from msdos era (bridgeboard +++)
Apple II
Sega Master System
C64 is quite good with Magic64
Etc

For the C64 the hard part seems to be the SID but it can be replaced by real SID to lower the burden on the CPU (SIDBlaser or ZorroSID).
Some skilled programmer could improve again on available emulators but most likely it needs to be done in assembly.

Magic64 was probably the best C64 emu on Amiga during it's time. didn't run to bad on 030/50 and ran great on 040/35 with RTG. It was handy to be able to toggle accurate drive emulation on/off as that was where a notable performance hit was.

FrodoPPC was spot on and ran great and until Vice was ported years later, was the best option if you had the hardware. WinuaePPC just about managed a stock A500 with playable speed (BlizzardPPC 040/25 - PPC/175)

The C64 Sensation CDs might be worth looking at if you want the real old stuff. It's worth noting at this point in time (late 90s) that similar C64s emus for pc targeting 486,low end pentiums were not much better.

Tried Vice and it fails to do anything, checked snoopdos and it seems to be failing loading cybergraphics.library which i do not have installed, does vice "Need" it, and if so whats the right way to make it work on a P96 setup?

[drHirudo]

You may also try the C64 emulators for Macintosh from the era under ShapeShifter, for comparison:
Examples:
C64 - https://www.macintoshrepository.org/17142-c64
Mac64 - https://www.macintoshrepository.org/67844-mac64
Commodore 64 Emulator - https://www.macintoshrepository.org/...re-64-emulator
Also the DOS C64 Emulators under PC-Task and DOSBox.
Don't expect too much though. Best for emulation of C64 on classic Amiga is still MagiC64.

[Retro1234]

I'm no expert on C64 emulators but i would of thought Frodo under Vampire or Pi would be best?

I guess with pistorm and Vampire a more recent emulator could be compiled.

Always thought it was a shame Commodore didn't invest in an official C64 emulator.

just found some more infos about GO64! and 'the 64 emulator' from Readysoft :

http://cbm.ficicilar.name.tr/commodo...-for-the-amiga

so the old Readysoft one should work also without extra accessories

it would be great a test on real hw to check if the disk works in first then

EDIT im readind into the disk files, it was a Randy Linden work?

i had a similar situation attempting to make work some Frodo old versions

the lack of detailed documentation is also a thing

I agree that Mac68k emulation on Amiga is fantastic
also the SMS emulation is enough good using amimastergear
even spectrum emulation is really good on zxamm and ASP emuls

but c64 emulation sucks,is yet very buggy
