A500 and games (not working)

[orange]

if the board was modified to see expansion as CHIP RAM, it would do it for both cards. and some games need 512 FAST RAM. you can see type of RAM with command: avail

srecno..

Hvala.
 
What do you mean by "if the board has been modified ... " ? What board ? The morherboard ? I've seen it naked plenty of times so far and it doesn't look like it has been touched by anyone. No hw alterations as far as I can tell. How can one tell anyways ? Maybe I'm not looking at the right angle.

It's dead easy to control - type avail into shell. What does it output?

Can you tell me what is the exact filename of one of the ADF games that do not work and I can try it on one of my Amigas.
I know of one game "Final Fight" that refused to work on all of my Amigas until I got NTSC A1000. This was the only one that the Final Fight worked. I gont know why, my A500 was about same spec before I modified it to 1MB chip ram.

He's referring to your A500 motherboard being modified. I don't know the exact procedure, but it's well documented. What this modification does is to turn your 512K trapdoor "fast ram" into "chip ram" (also called graphics memory) which results in 1MB chip ram.
Basically, some games require 1MB chip ram, in which case 512K chip and 512K fast just wouldn't work. This is where the motherboard modification comes in.
It's possible that some of your games are not working because you do not have enough chip ram available.

Ok, to name just a few:
 
Turrican II - The Final Fight_Disk1.adf
Syndicate_Disk1.adf
Cannon Fodder 2_Disk1.adf
Prince of Persia.adf
Lotus Turbo Challenge 2.adf
 
the intro loads fine, but afterwards it's just black screen and nothing happening.
 
Opposed to those, these work without any problems:
 
Another World_Disk1.adf (and 2)
Loom_Disk1.adf (2,3)
Leisure Suit Larry 1 - In the Land of the Lounge Lizards (remake)_Disk1.adf (2,3,4)
Dune_Disk1.adf (2,3)
Secret of Monkey Island, The_Disk1.adf (2,3,4)
 
and many others ...

It outputs (amongst other things):
 
chip max:  523264
fast max:  524288
total :     1047552

So there you have it, you have an unmodified motherboard...512K CHIP, 512K FAST (trapdoor expansion).

I tried "Turrican II - The Final Fight_Disk1.adf" in A500 rom 2.0, 1Meg chip, NTSC (this is normal A500 converted to A500+ with full ECS, I made a switch that I can boot in to PAL, I tested this game in PAL and it works fine too, music seems slower a bit) and A1000 Kick1.3, 512k chip, 1.5 Meg fast, NTSC, both work fine.

iirc, the games you listed as working require only 512K RAM (not sure about Another World though). I'd try more of 1Mb RAM games.
The 'usual procedure' is to re-seat all chips (or at least press down until you hear crack) and maybe replace capacitors, test voltages too.
There was also an "Advanced Amiga Analyzer", some of its tests can be used without extra hardware, perhaps it can help.

yaaa its true , pam machine is really helpfull, its gamimg part ,

A bit lost here ... the avail command stated that I have 512kb chip and 512kb fast ram. You think there's something wrong with my ram ? Which one ? The one on the MB, or the one on the expansion card(s) ?

could be, have you tried problematic games without the expansion RAM?

[nickoteen]

Yes. I've tried 'em without the extra ram. No go. I've pressed all the socketed chips until I heard a crack. Another no go. So, not a chip creep issue. I've even replaced the Denise chip with another one (don't ask me why, it sounded like a good idea at the moment), but it didn't work either.
 
To make the long story short ... some stuff works on my Amiga, some doesn't. I guess I'll just have to settle with what I've got.

[orange]

it is strange.. I'd run WhichAmiga in it and WinUAE, to make sure its the same config.

[nickoteen]

Ok. I'll try. Where can I get WhichAmiga ?
