HELP: Whdload memory requirements
Hi all,
I have an Amiga 500 (with 68010 CPU and a 1.3/3.1 kickstart switcher) with 512 kB expansion and a hard disk with 4 MB of ZIP ram. I have installed many games with WHDLoad anf they worked fine but I can't play games that require 1.0 MB ChipMem, like Xenon 2 and Barbarian 2. How can I solve this problem?Which is the difference beetween ChipMem and OtherMem? Thanks P.S. If I understand well, my Amiga 500 with my configuration has 512 kB of ChipMem and 4,5 MB of OtherMem?How can I upgrade ChipMem? |

I might be very wrong - The 512kb expansion is Slow mem -I always thought this was a type of Chip Ram? anyone?
-Maybe free some memory by booting without startup-sequence |

A500 for 1MB chipmem needs some serious hacking (IE rev 6A can have soldered another 4 chips on board directly).
there is also some hack howto use your 512k expansion card as additional chipmem too. see here http://aminet.net/package/docs/hard/a500chip (swich JP2 and cut JP7A) |

Of course. The hack is not really to the RAM expansion but to the A500 motherboard.
But it only works if you have a 1Mbyte Agnus chip (naturally). If you do not have one, in addition to the modification to the motherboard you'll also have to buy a new Agnus chip. Quote:

There should be no requirement for the WHDLoad install of Xenon 2 to require 1meg of chip ram as the game runs in 512k

Personally i'd contact Wepl to see if he can change his slave, the game never used 1meg chip ram.

I wonder if the slave was based around the CDTV version and that is why there is a 1Mbyte Chip RAM restriction? Probably not looking at the history.

Don't know, myself i'd have included a separate slave for CDTV over the standard A500 versions.

I put the JST version of Xenon 2 in the Zone this seemed to work with Quickstart A500 +4mb fast +3.1 Roms under WinUae.
:Theres 2 versions in the Zone try the JST version first. |

P.S. The doc says : "First off, it is required you have a revision 6A motherboard for this pro- ject. It will work with others, but requires a 1mb Agnus chip and also re- quires cutting a trace, which I am not familiar with at the moment." So, all revision 6A motherboards have a 1MByte Agnus?
