A new version of the firmware for the AVGCART (SD multicart for 8bit Atari) by tmp is released.

The AVGCART is a FPGA based multicart for 8bit Atari computers, extensible with SIO and/or ECI/PBI cables.

• supports CAR (cartridge dump) files up to 1MB and most bankswitching types
• supports XEX (executable) files
• supports ATR (floppy image) files (read/write) – support is limited without an optional SIO or ECI/PBI cable due to Atari cartridge port constraints (e.g. SW that uses RAM under OS does not work)
• supports ATX (protected floppy image) files (read-only, SIO cable required)
• supports CAS (cassette) files (SIO cable required)
• supports AVF (video) files
• supports PDM (audio) files
• fast file search, file shortcuts, randomizer and tons of other features
• when used with optional ECI/PBI cable, it can expand ATARI memory to up to 576kB, it can also provide extra 48kB RAM to stock 16kB 600XL machines (some limitations apply)
• firmware upgradeable via SD card (no additional hw needed)
• SIDE2 emulation (compatible with U1MB and SpartaDOS X)
• ability to stack emulated cart with emulated SpartaDOS X cart, together with SIDE2 emulated HDD
• unlike some other products, most of the functionality is running inside the cart and not on the host machine’s CPU which makes it faster and more versatile (it can do stuff in parallel with host machine without having to gain 6502 control and doesn’t require soldering extra internal upgrades like Ultimate 1MB for some basic functionality like ATR emulation or memory expansion)
• compatible with 600XL, 800XL/XE, 65XE, 130XE, XEGS (cartridge shell is too wide for 1200XL, bare pcb will fit, it is also too tall for 800, can be used with cartridge door opened and door switch triggered)
