    i've checked osb source and it kinda makes sense, it checks very early (and quickly) where the ram ends (before the cart is ready), then does the heavier stuff (hw init, mem clearing) and although the cart becomes ready before it actually checks for its presence, it doesn't bother doing so if ram was detected there at the beginning, that's why 32kB and 48kB behaves differently

    normally i'd say it could be the time avgcart needs to initialize (this was already addressed in the past when i learnt there was such issue with either QMEG or Atari 400 (OSA) being way quicker to initialize than the other OS') but since you're saying that less memory works and more doesn't, it's probably something else (more memory should take more time to clear)

    it could be related to that special way s4/s5 works in 800 but it's still weird that nobody complained about it before (ok a8isa apparently did)

     

    i'll have a look at it

    that video is still more "how" than "why"

     

    something like that (with some prior setup required on the sd card (assigning car files to some kind of perm (per card) slots)) would be probably doable with reasonable amount of effort but i still feel you'd be the only user of that functionality in the universe (waiting for the masses to prove me wrong)

    it's not a matter of the api not being documented, there's no such api because there was never need for one

     

    i understand what faicuai would want to do, my question was merely "what would it be useful for?", expecting answer like "i'd run sdx, from there i'd "mount" cart <enter name here>, then i would exit back to sdx and "mount" cart <enter different name here> and it's useful to do that without going back to cart's selector (without a reset) because <enter reason here>"

     

    if it sounded useful, it could get to my list of things to consider but without seeing any practical advantage of implementing that, there's not much motivation

    Now, when inserting AVG cart and cold-booting on left-cart port, does it maps fully on $8000-$BFFF region? Or, asked differently, if I have a right-cart plugged on $8000-$9FFF, would AVG claim first that address space (thus rendering the right-cart inoperable)?

     

    I ask because Ultimate/SD had this problem, and it was later corrected. Today it works perfectly.

    i vaguely remember reading something about, some oddity with s4(?) signal on 800 or something like that, frankly i have no idea since i don't own 800 and nobody complained so either it does work or (more likely) nobody cared (to report)

    in the latter case it should be easy to fix should someone report the issue and could test the potential fix

    Is this what you refer to?

     

    Or is that a different / new feature, not related to SIDE emulation?

     

    no, SIDE2 emulation is an old functionality that's been there for years

     

    you can run a special cart image (s2sdx3.car), which will emulate SIDE2 including ROM containing SDX, that will boot SDX and will also emulate necessary stuff in CCTL so SIDE.SYS driver included in that car file will able to access SD card as if it was CF card inserted in SIDE2, that's useful for use with stock machine

     

    the other option is to enable "light" SIDE2 mode where only CCTL stuff is enabled (via SHIFT-S in AVGCART menu or cart button held on power on or auto side mode where it automatically drops into that mode on power on), this can be used with U1MB where U1MB will detect the SD card as HDD and from there you can use it anywhere where it would work with U1MB+SIDE2 setup

    I was doing some tests today, stacking Action!, MAC/65 and OSS Basic XL seems to work, OSS Basic XE 4.1/4.2 doesn't start (some weird hacked 7.2 version does tho, I need to look into that), what are some other carts that could use stacking with SDX?

    I recently received an AVGCART and have gotten it preliminarily set up. Besides emulating game cartridges, my other big reason to use AVGCART is to dive into using SpartaDOS X. I noticed on tmp's YouTube channel a video showing off Action! being run as a stacked cartridge on top of SDX (https://www.youtube.com/watch?v=6vc6JYne79o). Perhaps I have simply not read the manual closely enough, but is the ability to use stacked cartridge images currently in the production firmware?

    sdx stacking is not in the current non-beta fw (0020) and i think it's also unfinished (i'll take a look whether it's a easy fix to make it work properly since it's currently hardcoded for type 43 sdx images (128kB))

    if you're looking into stacking OSS carts, somewhere in this (mostly off-topic) thread is an archive with pre-stacked SIDE2 SDX + OSS carts, those should work with 0020, i'll try to find that

     

    EDIT: i've uploaded them here

    In any case, I give hearty thanks for such a well-made device!

    thanks!

    With 

    Hello Dan, with the AVG cart and the SIO cable, how do you select multiple ATR files?

    TAB or SHIFT-1 to 4

    Does it have some sort of user interface that boots when you plug the SIO cable into the port on the back of the Atari, and you can then select the various ATR files?

    you select ATR files in AVGCART's file browser and then boot, after that you can use cart button to cycle selected ATR files among assigned drives

    Also, I have a stock Atari 800 XL with no memory expansion. Would AVG and SIO work for multiple ATR games? Thanks!

    when using SIO cable, no atari ram is used by the cart so if the game runs on 64kB, it should run

    Hmmm, depending on how much power this device consumes, you may add power to PBI pin 47 or 48 and then power this device internally or simply use an external power supply.

    i'm aware of the options (there aren't many), i just don't like them ;-)

    Open for adding features? AA users will surely give you dozens of ideas what could be added. I would like to see some kind of AIO device, meaning a PBI device that is more than just one upgrade (IDE-upgrade/interface, XRAM-upgrade, sound-upgrade/sound-add-on, gfx-upgrade, OS-upgrade/switcher, etc. all-in-one).

    i'm open to any ideas, of course i will cherry-pick those i like ;-)

    5 hours ago, Mathy said:

    Would that be user selectable or do you decide which one it is going to be?

    there's enough ram to have both enabled at the same time (although i doubt there's any sw that can use both at the same time (ok, sysinfo can detect them both but that doesn't count)) so user configurable

    it seems that those atr files don't boot if HSIO is enabled in the cart (any divisor), try to disable it if you have it enabled (CTRL-H)

    (if you used multiple sd cards, that could have caused that OSXEX2 confusion since settings are stored on the card)

     

    not sure if that HSIO issue is AVGCART specific or it's some spartados bug, i'll need to check what's going on there

     

    correction: it works with divisor 8 and higher which is most likely expected behavior since spartados is known to have issues with lower divisors

    is there any difference if you don't select the atr with shift-1 first? (there's no need to do that if you're starting only a single atr and you're not trying to use it with e.g. car file)

    (i'll test it but i need to connect my atari setup first)

    @tmp: What kind of hardware is your new Avatar?

    it's a prototype PBI device, currently it does only OS switching and ram expansion (1088kB PORTB and/or 4MB AXLON), still trying to decide what features i will include (and how it will be powered on 800xl, thank you Atari for that)

    And errrm, when will the new/latest firmware 0.21 (or 0.22) be released to the public ?

     

    (No complaint, just hoping for an easter egg / easter gift.)

    unfortunately no firmware will rise this easter

    SIO cable: I just wired up the cable and it’s working for other titles.

     

    I selected the disk with Shift-1, then Option-Return.

     

    I removed the OSEXE2 file and now it boots!

     

    The docs at De Re AVGCART suggest you can leave OSEXE2 and use SHIFT-RETURN to enable it but I had to remove it from the SD card altogether.

    it must be something else because the presence of OSXEX2 does not influence which atr emulation method is chosen (it is based on cable detection and state of the shift key)
