How can I play Sega games on my Amiga?

[A4000_Mad]

Hi,

The first computer I ever took notice of was a ZX Spectrum and a guy was playing Jetpac on it. I had a go and was hooked. So I bought the ZX Spectrum and all his games off of him.

I now how a Speccy emulator for my Amiga and can play my old favourites perfectly   :-D





Now I would like to emulate a Sega Megadrive so that I can play my favourite game Whip Rush and my kids can play Sonic The Hedgehog etc. BTW... Has anyone else played or completed Whip Rush?



So how can I make the Amiga emulate a Sega Megadrive please?

Thanks,

A4000 Mad

there are genesis emulators for the amiga i think you need a fast 040 for anything although most emulators recomend an 060 or ppc.
amigenerator is one it requres a ppc amiga with cybergraphics support.

There is quite fast snes emulator for amiga but none of genesis emulators are usable with 040

Theres a good snes emu?All i have ever really seen for 68k is 8bit emulation...what snes emulator can you use on amiga with 68k?i have an 060..
Mind you i doubt it will be very playable on an 060...

Wow - Jetpac!!!!! I remember that from way back when .....

Have you played:

Trans-am
Manic Minor
Jet Set Willy

the c64 was king but the speccy had some cool games too

The Genesis emulators for the Amiga all try to re-emulate the 68000 CPU, so they end up being about as fast as 68K UAE: extremely slow and unusable.

If someone were to write one that used the ShapeShifter or BasiliskII core, then we'd be in great shape...

[utri007]

Good ? no but fast yes those games that work are quite playable

It was mysnes if I remember correctly?

[KThunder]

the genesis has a 68000 cpu wich of course is 32bit internally with many registers and many instructions. it also has a z80 cpu which has many registers which can be pared to be 16bit and it has many 16bit instructions.

that is much more complex than an snes which has a fairly simple 65816 16 bit cpu

i think that is what makes the genny much more difficult to emulate. even though the miggy has a 68k you have to emulate the gennys cpu because you have to controle it very precisely to sync everything,

a couple of snes emulators are very playable on 040's genesis ones all need ppc from what ive found now.

@ hektic

I've probably got those games in my Speccy emulator drawer and will have to give them a go to jog my memory of them.


@ all

Many thanks. I'm using an A4000 running WarpOS with Phase 5 Cyberstorm PPC 604e 233Mhz with 060/50 and Cybervision64/3D. The Cyberstorm PPC is actually in what I call my test rig A4000 with Workbench 3.1, 3.0 ROMS and Buster 9 :oops:

I've got Amigenerator from here:


http://www.amidog.com/amiga/amigenerator/


And some ROM files for Sonic1, Sonic2 and WhipRush.


The file names are very long with spaces as you can see below. You have to start it with a command line so I made copies and renamed them as Sonic1.zip, Sonic2.zip and WhipRush.zip to get rid of  the spaces. Hopefully this won't be a problem?





Typing 'Amigenerator.exe Sonic1.zip' triggers NEWMODE. After choosing 640x480 16bit the screen changes and it looks as though the program has started ok. But after about 1.5 seconds it goes back to shell with the report "Something has gone seriously wrong @ 006600E7"

Typing 'Amigenerator.exe Sonic2.zip' gives a black screen momentarily followed by the report "Invalid instruction @ 0000010C".

Typing 'Amigenerator.exe WhipRush.zip' gives a black screen momentarily followed by the report "Invalid instruction @ 00000168".


Here are some Scout screengrabs of my system......





Hmmmm... It appears that I am using Picasso96 drivers instead of the required Cybergraphx. Prehaps this is part of the problem?

I'm pretty new to the PPC but I can tell you that the WarpOS version of FroggerNG is working perfectly for video and movie playback. ShowPPC for picture display and AmigaAMP PPC version are also working fine.

Would it be faster or even possible to execute the 68k code of the Genesis natively and just catch hardware and special system calls?  The Z80 and Yamaha chips would have to be emulated, still.

[Matt_H]

@ LoadWB

Yeah, that's what I was suggesting by using one of the Mac emulators as a framework - they use the Amiga's own 68000.

@ A4000 Mad

Try unzipping the files first ;-)

[Amigaz]

Amigenerator, Yes!

There's your answer, been using it alot...but only the AmiGeneratorT.exe since the plain exe is too slow  :-(
It even works in MorphOS PowerUP but there's no sound  :cry:

[A4000_Mad]

Try unzipping the files first ;-)

Thanks. I tried that last night but Dopus reported that they were encrypted. But I've just chosen to open the file for Sonic 1 using a PC. This shows two files called 'romguy.html' and 'Sonic The Hedgehog (W) (Rev01) [!].bin'

However, if I try to copy either of them to a Jaz disk to take to the A4000, a box appears for me to enter a password.

BTW I'm using Mame060 to play old arcade classics like Mr Do, Berzerk, Bombjack and Mooncresta. This is really cool but the files *do* remain zipped. Yeah I've tried putting the Sega roms into Mame060, as you do, but they aren't recognized.

@ AMIGAZ

I've tried AmiGeneratorT.exe as well with no joy. Can you confirm whether the Sega game roms remain zipped or not please mate?

There is a very good MasterSystem emulator (i know, not as fun as MegaDrive but..) called AmiMasterGear iirc. Doesn't work with gfxcards though.
