Ultimate Cart - Users thread

Recommended Posts

Yes there is. It appears to be more stable  in my experience. I use a number of add-ons, other carts that stack and the like. I didn't do a run down of what changed, I just know it now works all the time (basically 99.999% as opposed to 98% of the time) , no matter what configuration things are in.

Does this patch also incorporate the bus contention fix described here and available here?

Actually, I see that these patches are very similar, but the address ranges are slightly different ($8000-$9FFF here in this thread, but $8000-$BFFF in the other thread I linked).

 

Which is correct?

@Faicuai , @Vigo perhaps the two of you can get together on this. I am not sure which I used. Faicuai verified operation on his real machine last I knew.

Sorry for taking so long to catch this one...

 

...But this link will take you to the correct load for Ultimate/SD (effectively fixing bus-contention on $8000-$9FFF, only revealed when operating Ultimate/SD on 800's dual-cart bus:

 

 

I would recommend the above fix regardless if you run (or not) the cart on a 800.

Hi @Faicuai :

 

There is a problem reported between the Firmware of the Ultimate Cart and the 512kb Memory Expansion developed by the user tf_hh, specifically the version 4.4 of the hardware. The situation is the following:

  • If everything work as expected, the Memory should be automatically detected when turning on the Atari, and it should work with any Cart.
  • However, the version 4.4 of the hardware doesn't work properly with a stock Ultimate Cart (it has not been tested with the new firmware). The developer stated that the Memory works properly with other carts, and also there was a change since the version 4.2, regarding addresses that were causing trouble. The version 4.2 works fine with the Ultimate Cart, and it's not documented what addresses were changed in the version 4.4.
  • The developer of the Memory stated that his hardware v4.4 is a "state of the art" device, and the problem lies in the Firmware of the Ultimate Cart.
  • He also suggested to test the memory with a SIO device, in order to see if the problem is the Ultimate Cart or the Memory. But due to current logistics problems, it hasn't been possible to get a SIO device in order to make a test.
  • There are some videos showing such behavior of the Ultimate Cart and the Memory Expansions, in post #183 and #187 of the hardware topic.

The problem seems to be the addresses that are being used by both devices.

 

Any idea what could be the problem in the Ultimate Cart regarding its addresses?

 

Personally without any technical knowledge of both devices, the developer of the Memory Expansion is heavily stating that the problem lies in the Firmware of the Ultimate Cart.

Hi there!

 

I don't own / use tf_hh's 512 KB expansion, although I do own his (great) SysCheck-II board, which does come with 512 KB of on-board RAM.

 

The problem described above could be initially (and quickly) traced provided two known sets of info:

 

1. HW-registers map in use by Ultimate/SD Cart (for both pre-boot / in-menu and post-boot / emulation modes).

2. HW-registers map in use by tf_hh's expansion.

 

I do know (factually) that Ultimate/SD actively uses $D510 (for FPGA command-in control) and and $AFF0 for FPGA status-out purposes (which I am using on my own Control-Extensions for this cart). Other than that, I have been wanting to know myself (for sure) what other HW registers may be also used by Ultimate/SD, at different operational stages.

 

Having said that, if SysCheck-II on-board's RAM expansion behaves identically to the one you mention, and also maps to the same HW-registers set, then I may be able to test on my end... but keep in mind that I will be testing on U1MB-equipped XLs and Incognito-equipped 800's via PBI bus.

It's known that Memory Expansion v4.2 and v4.4 are different, so nothing guarantees that SysCheck will behave the same.

I can't provide information about HW-registers. Maybe @tf_hh could add a technical detail about the Memory Expansions, in order to have a smooth firmware for the Ultimate Cart that is compatible with other hardware expansions.

So the $8000-$BFFF patch is incomplete? That is the patch I currently have applied.

FYI:

 

Tried two (2) revised versions of firmware-loads for Ultimate/SD and the ONLY one that allows booting a right-cart with Ultimate/SD plugged as left-cart is the version that I pointed to.

 

Not sure exactly what is the issue you are chasing, but if you want to address the problem mentioned above, the link I provided solves it.

 

Cheers!

I have a question:

what about .atr and .bas files?

can they be loaded into this cart and played? (in a 800XL to be precise)

Thanks

There is no atr support on this cart

Hi, I'm looking for an XEX rom download of this game 'Crypts Of Terror' for the Ultimate Cart in my 800xl. Enjoyed this game a lot back in the 80s but can't find file format anywhere that's compatible with my Ultimate Cart. I've tried the conversion tools too without any joy.  Supported file formats are CAR, XEX, ROM and BIN.  If anyone knows of a download of any on these formats anywhere or can create one for me or advise how to create/convert one that works with the Ultimate Cart, ideally XEX format, that would be fab.

If you're talking about Crypts of Terror from Inhome Software, you won't find any of those formats available. It was a BASIC game released on disk or cassette. The only way it may possibly work is if someone wrapped it in some sort of loader software as an xex maybe, but I'm not sure if anyone has ever done anything like that for BASIC games.

Does anyone have the cable and the desire to test?🙄
to see if it is possible to add more CAR support 😅
