Sim City 2000 End of slowdown

[FloLore]

Hi EAB,


I would like to share with you how (with the Winuae emulator) to launch it with as much fluidity as the PC version at its best. 68040 JIT FPU & NTSC, 2M chip, 8 Fast Ram, 32 bit Chip 16Mb (very important).


For a few days, I wanted to play this game again on Amiga, but I absolutely couldn't stand these slowdowns.



Good game

becasue Amiga version is bad programmed and bad optimized,

640x512 (or even 640x400) is just never going to be fast with native chipset modes. The game doesn't seem to be especially badly programmed (looks like a C port from disasm), and actually has fairly advanced C2P functions for the time. OS functions are used for nearly everything, so hard to fault them when it's just a late-ish port.


With RTG it's very fast and playable with WinUAE. A bit meh speedwise even on my pistorm though.


Looked at patching it recently before I realized there was already a patch on aminet. That one requires modepro to work though, so maybe I'll consider patching the patch..

AGA version is not 256 colors and as it's a direct porting from Mega Drive, i suspect that you have 64 colors or maybe less.

with Pistorm/Amithlon/WinUAE is good and playbale, but this game was developed to run on stock A1200HD with some Fast RAM.
However if you are able to patch it to have a better improvement to handle 640x512 will be a big thing.

Mega Drive port? You meant windowed PC DOS port, right? If you must play it on a real Amiga, just use the Shapeshifter emulator & Mac version. Problem solved.
