are a strict requirement for any C64 cartridge lover. Since the ''1541U'' emulates a range of freezer cartridges and allows re-flashing them it is a perfect platform for testing ROMs on the real machine. Cartridge emulation is pretty good and should suit most requirements. This emulation also made the ''1541u'' enter the charts here. There are some problems left as with any other hardware but since this baby can be updated and firmware is publicly available we see a bright future for it.

== Known Problems ==
== Known Problems ==


=== Freezer bug ===
Please understand that due to the nature of FPGA based hardware, many problems might get fixed with a firmware update at some point. For this reason we list only "persistant" problems here, like actual hardware bugs or long standing firmware bugs. For details please refer to the [http://www.1541ultimate.net/ 1541 Ultimate website].
 
===1541U===
 
==== Freezer bug ====


''TODO''
There have been long standing issues with the freezer logic, affecting both emulated cartridges and the menu system. Common symptoms are freezer not reacting at all (perhaps connected to DMA loading), or crash when returning from the freezer to the running program.


=== Ethernet bug ===
<small>
see [http://www.1541ultimate.net/content/index.php?option=com_fireboard&Itemid=4&func=view&id=8178&catid=9] (requires registration)
</small>
 
==== Ethernet bug ====
This is a hardware problem with the -plus version of the 1541U board. When the CS8900a chip is enabled, the RAM under the i/o area can not be accessed correctly, which makes some operations impossible (such as transferring binaries to that area using codenet)

''"Ethernet will never work 100% on the 1541U-I for ALL C64's out there. This is bus-timing related and could only be fixed if some of the timing is revised and other concessions are made."''

<small>
see 1541U-II Bug List [[Media:BugList_-_2014-05-19.png|local copy]] (retrieved 19 Mai 2014)
</small>
==== Cartridge problems ====
* regular 8k-game and Ultimax cartridges do not work
* when an unsupported CRT file is loaded, the menu program shows a message, and then the fpga core locks up, requiring a power cycle.

    Programming See 1541ultimate.net
    Attention please!
    The cartridge described in this article is under constant active development - for recent news and data please check: 1541ultimate.net

    1541U is one of the ultimate cartridges for the C64 and regular checks at 1541ultimate.net are a strict requirement for any C64 cartridge lover. It started in 2008 as a hobby project by Gideon Zweijtzer, who then founded the company "Gideon's Logic Architectures" in January 2009.

    Since the 1541U emulates a range of freezer cartridges and allows re-flashing them it is a perfect platform for testing ROMs on the real machine. Cartridge emulation is pretty good and should suit most requirements. This emulation also made the 1541u enter the charts here. There are some problems left as with any other hardware but since this baby can be updated and firmware is publicly available we see a bright future for it.

    Following info mostly from the 1541Ultimate Website:

    Hardware Specifications

    The basic hardware platform went through 3 revisions so far:

    1541U

    this describes the first version of the hardware, produced from 2008 to end of 2009.

    • Board size: 68 x 100 mm
    • 250k-gate FPGA
    • Full size 6-pin DIN connector (IEC)
    • 512 kB SRAM
    • 2 MB Flash ROM
    • 16 MB SDRAM
    • Full size MMC / SD card compatible (Mini/Micro SD possible with adapter)
    • Stereo audio output
    • 6-pin expansion pin-header for connection to tape port (for C2N emulation), or other future features.

    1541U-plus

    as above, with the following differences:

    • 32 MB SDRAM (+16MB for REU)
    • CS8900a ethernet interface (optional since second batch)

    Note: only a small number non-plus boards (with just 16MB RAM) was produced, all later boards were -plus boards.

    1541U-II

    this describes the current version of the hardware, produced since 2010.

    as above, with the following differences:

    • Board size: 62 x 84 mm (about 30% smaller than the 1541U)
    • Sturdy plastic case, enforced with glass fiber
    • 700k-gate FPGA
    • MicroSD card compatible slot (instead of a full-size SD)
    • USB host port (supports Mass storage class only)
    • real-time-clock function, for correct file time and date
    • ethernet was removed from the hardware

    1541U-II+

    slightly revised hardware, available since september 2016.

    • Sturdy ABS plastic case
    • Slightly bigger and faster 1M-gate FPGA
    • 5 MB Flash ROM
    • 64 MB DDR2 SDRAM
    • SD card slot was removed
    • Improved Audio codec (24 bit/96 kHz, for sampled sounds and SID emulation)
    • Full size 6-pin DIN connector (IEC)
    • Audio input added (currently not yet used)
    • Speaker built in
    • 100Mbps Ethernet adapter built in (NOT yet CS8900a/RR-Net compatible)
    • Micro USB for external power
    • Three USB host ports
      • Specialty USB 3.0 port with USB 2.0 signals for storage device OR cable to tape adapter board (for C2N emulation), or other future features.
      • revised tape-adapter, connected via a USB port
    • Dual Flash (no more worry that a software bug or upgrade failure leads to a bricked device)

    Known Problems

    Please understand that due to the nature of FPGA based hardware, many problems might get fixed with a firmware update at some point. For this reason we list only "persistant" problems here, like actual hardware bugs or long standing firmware bugs. For details please refer to the 1541 Ultimate website.

    1541U

    Freezer bug

    There have been long standing issues with the freezer logic, affecting both emulated cartridges and the menu system. Common symptoms are freezer not reacting at all (perhaps connected to DMA loading), or crash when returning from the freezer to the running program.

    see [1] (requires registration)

    Ethernet bug

    This is a hardware problem with the -plus version of the 1541U board. When the CS8900a chip is enabled, the RAM under the i/o area can not be accessed correctly, which makes some operations impossible (such as transferring binaries to that area using codenet) "Ethernet will never work 100% on the 1541U-I for ALL C64's out there. This is bus-timing related and could only be fixed if some of the timing is revised and other concessions are made."

    see [2] (requires registration)

    1541U-II

    see 1541U-II Bug List local copy (retrieved 19 Mai 2014)

    Cartridge problems

    • regular 8k-game and Ultimax cartridges do not work
    • when an unsupported CRT file is loaded, the menu program shows a message, and then the fpga core locks up, requiring a power cycle.

    Listing software that requires one or another special feature only available on "modern" hardware and/or emulators, such as the 1541U, Chameleon or VICE.

    16MB REU

    Note: 16MB REU is also implemented by the Chameleon and can also be emulated by VICE.

    Ultimate Audio

    "Ultimate Audio" is a custom 7(?) channel PCM output, which is available in 1541U-II Firmwares 2.5+

    Ultimate DOS

    "Ultimate DOS" is a custom command interface for accessing files on the SD card, which is available in 1541U-II Firmwares 2.5+.

    Notes

    • Wikipedia deleted the page on the 1541 Ultimate (twice actually). Due to "Unambiguous advertising or promotion" the last time. Well - WiPeD 1541 Ultimate tries to recover it.
