I'm pretty sure it does, did you load it with attach cartridge image?nbla000 wrote:... and Vice doesn't work properly for protected Ram images that try to write to itself example Omega Race Original
Moon Patrol images doesn't start in real Vic-20?
Yes if you attach the cartridge image works but if you try to load it from a disk image in emulation LOAD "OMEGARACE",8,1 as the real Vic-20 doesn't work.tlr wrote:I'm pretty sure it does, did you load it with attach cartridge image?nbla000 wrote:... and Vice doesn't work properly for protected Ram images that try to write to itself example Omega Race Original
Yes may be the memory expansion but i've tested it with 3 different check programs and with other games images that uses banks 3/5 too and only with Ms-PacMan i've the same problem, so i need only to buy another one to test.carlsson wrote:there is a problem with nbla's memory expansion or reset button
For the reset button i've tested 4 different user and serial port reset.
5 different disk images trasfered 5 times to 5 differend 1541/1581 disks works on VICE, so i don't think so.carlsson wrote:Or the files transferred from Zimmers were buggy.
Very interesting, yes i've used the same PSU, may be the PSU? in any case i try other PSUs this week.Boray wrote: maybe your PSU if you used the same one when you tried with your vic-20s....
Finally something to do this week-end non only Beach, Beer and Soccer (Italy in semifinals and very hot weather)
Obviously i will try to find at least a new 16k switchable or 32k memory cartridge.
Someone has one to sell me?
FINALLY SOLVED THE PROBLEM!!!!!!
The problem was the switch settings on the 32K cartridge.
Since i haven't the istruction i've tested it to search the 32k switch position and 8k only in bank 5 switch position, for 32k i've found the 1/2/3/6 combination and for 8k only in bank 5 switch 1 only, the 32k go well for all the cartridge image i've tested except for the cartridge that need 8k in bank 5 only obviously and for all normal games that need 8k/16k/24k but not for Moon Patrol and Ms PacMan.
So using various memory test programs i've tested all switch combination and i've discovered another combination for 32k and other very interesting like banks 3/5 only or 2/5 or 1/2/5 and so on, well using the switch position for banks 3/5 only or the alternate switch position (2/3/6) for full 1/2/3/5 banks the game works. If someone use a cartridge like this without 2k eprom and using 32k memory instead of 64k i may send all switch combinations test result.
By the way, someone know which is the vendor of this expander? The symbol remind something?

Zero Electronics advertised a 64K RAM + 2K EPROM expansion, and their logotype looks a bit similar, but not identical. Still, it could be a Zero expansion.
The reason why some programs don't work with block 1 enabled in particular is if the VIC has relocated the pointers to screen memory, and the cartridge doesn't set them itself, but assumes a certain configuration. I should be able to repeat your failure now when we have an idea what the problem was.

No, even with all blocks 1/2/3/5 enabled, Moon Patrol works fine on my VIC. Maybe the optional EPROM on your cartridge maps somewhere and disturbs things?

Switch 1/2/3/6 and switch 2/3/6 both enables banks 1/2/3/5 but only using switch 2/3/6 moon patrol works, may be some predisposition for 2k eprom the problem, in any case thanks to every one for helps.
