Programming See Tech Section

The Final Cartridge by its name and its successor, the very popular Final Cartridge III, are likely the second most spread cartridges or merely cartridge family after the Replay series. Final Cartridge was developed in Holland by H & P Comp (Home & Personal Computer) with the first versions hitting the market in the middle of 1985. They continued development and small updates were spread with new production runs as it appears. There were five different ROM versions of the Final Cartridge III until now for example.

Classic. Final Cartridge III

Versioning your cartridge is not that easy in this case. Checking the so far available screenshots to the right you will see that FC1 and FC2 use the same menu with just the scroller revealing a II. The FC+ went unemulated for a long time and is a pre-FC3 as a ROM dump by Markus Brenner approves. It is carrying the string "(C) SJATON80 FC3" on an otherwise empty and inaccessible eprom bank. FC1 through FC+ share much of the same hardware but the FC+ has a slightly different wiring leading to different behaviour. The overall payload of FC+ is 24kb put on a 32kb eprom while FC2 and below came with 16kb.

A larger update on the ROM size and hardware was done with the release of the Final Cartridge III (FC3) coming with 64kb of eprom content. Banking was simply not avoidable anymore. The FC+ was sold for just a short time and it appears that quite some code also made it into the FC3 in very little time but investigations are still pending on this issue. It would have made sense to rewrite parts of the cartridge at this point just taking over portions of the previous ROMs.

Some confusion could be added here but unless we found the correct ROM backing us up we will stick that into the Trivia section here.

  • FC1 has the usual fast loader, freezer, monitor, fkey support and dos wedge stuff while on FC2 ROMs it looks like just a few drive handling and timing things got changed. About 300 hexbytes and no apparent change on functionality so it could as well be just FC1. Additionally the person dumping the ROM added the string "noddy 260788" which hints a date when the FC3 was already available. We therefore strongly demand owners of pre-FC3 cartridges to run TFC FC1 FC2 FCplus ROM Dumper and pass the output file to us.
  • FC+ has the string "(C) SJATON80 FC3" on the _unused_ eprom bank - most of the rest pretty much looks like an enhanced FC2. One of the two versions we found also has "EPROMMER II" on some unused area - A hint to the used eprom programmer software. The changes on some commands and a large part of the code makes us believe that the code this FC+ is based on is coming from The Final Cartridge Internal. Richard nicely provided us with the eprom dumps of these and you may find them on the archive for further investigations.

The two versions of FC+ found so far contain a few changed routines but again no major function was added. FLOAD and TLOAD were introduced after FC2. Again: if you own this cartridge please run TFC FC1 FC2 FCplus ROM Dumper and pass the output file to us.

BEFORE

you skip to the downloads below consider having a closer look at the Final Cartridge category as it has quite a few more paper magazine reviews, adverts and photos you may miss otherwise.


Tech

Final Cartridge 1 - The Final Cartridge
Final Cartridge Advert

final.c (should) explain: 

   The Final Cartridge 1 + 2

   - any access to IO1 turns cartridge ROM off
   - any access to IO2 turns cartridge ROM on

finalplus.c explains the FC+ handling. A cartridge which caused some headache during implementation. 

Final Cartridge Plus

    - reset button, cart enable switch
    - 32K ROM, of which 24K are used

        EPROM $2000-$4000 is visible at $e000-$ffff, if enabled
        EPROM $4000-$5fff is visible at $8000-$9fff, if enabled
        EPROM $6000-$7fff is visible at $a000-$bfff, if enabled

An NMI can is triggered by the cart, if address $0001 is written to and the cartridge is enabled.

The cart can also be disabled by software by setting bit 4 to "zero" when writing to $df00-$dfff.
cart ROM at $e000-$ffff can be disabled by setting bit 5 to "zero" when writing to $df00-$dfff.
cart ROM at $8000-$bfff can be disabled by setting bit 6 to "one" when writing to $df00-$dfff.
Bit 7 of a byte written to $df00-$dfff can be read back from the cartridge if enabled (kind of a memory cell).

final3.c explains the FC3 register: 

   The Final Cartridge 3

   - 4 16K ROM Banks at $8000/$a000 (=64K)

        Bank 0:  BASIC, Monitor, Disk-Turbo
        Bank 1:  Notepad, BASIC (Menu Bar)
        Bank 2:  Desktop, Freezer/Print
        Bank 3:  Freezer, Compression

   - the cartridges uses the entire io1 and io2 range

   - one register at $DFFF:

    7      Hide this register (1 = hidden)
    6      NMI line   (0 = low = active) *1)
    5      GAME line  (0 = low = active) *2)
    4      EXROM line (0 = low = active)
    2-3    unassigned (usually set to 0)
    0-1    number of bank to show at $8000

    1) if either the freezer button is pressed, or bit 6 is 0, then
       an NMI is generated

    2) if the freezer button is pressed, GAME is also forced low

    - the rest of io1/io2 contain a mirror of the last 2 pages of the
      currently selected rom bank (also at $dfff, contrary to what some
      other documents say)

While some of the above information is derived from the excellent AAY64 - FC3 I/O space and kernal vectors and FC3 I/O register - the VICE documentation is likely more correct.

The Final Cartridge III Internals written by M.Steil may also be known to some people - whoever is reading up on it should consider reading the Final Cartridge III Internals Errata as well.

  • Final Cartridge Internal 2764 Eprom.bin - please check the supplied txt
  • Final Cartridge 1 1986 KillerCart Texthack.bin and .crt - nothing changed apart from the scrolling text vs Final Cartridge 1 v2 1986
  • Final Cartridge 1 v1 1986.bin and .crt
  • Final Cartridge 1 v2 1986.bin and .crt
  • Final Cartridge 2 1986 polish.bin and .crt - please check the supplied txt

  • Final Cartridge 3 1987-11.bin and .crt
  • Final Cartridge 3 1988-05.bin and .crt
  • Final Cartridge 3 1988-12.bin and .crt
  • Final Cartridge 3 1988-13.bin and .crt - This is a custom 1988-12 hack for a better emulator experience it appears. The 1-byte hack reverses behaviour of the reset routine so FC3 always starts in toolkit basic. To enter the FC3 GUI you need to hold down Run/Stop on Reset.
  • FC3 Development Disk.d64 - includes assembler sources for programming own programs utilising the FC3 GUI (Check supplied .seq file for details) found at cascade64.de
  • FC1DUMP CARTRIDGE DUMPER V1.1 by Markus Brenner to be used for The Final Cartridge, Final Cartridge II and Final Cartridge Plus (incl. sources)
  • FC3DUMP CARTRIDGE DUMPER V1.1 by Markus Brenner to be used for Final Cartridge III (incl. sources)
  • Kill FC3 by fieserWolf/Metalvotze
  • The Final Cartridge III Packer! by Shaver/Slash Design does not require a FC3 but is the cartridge packer as a stand-alone program
  • Final Cartridge III Backup Update by J.Man for Sky Networks (1996) found at cascade64.de
  • FC Capture v1.5 (for FC3) by Solairis of Sky Networks (1997) found at cascade64.de
  • FC G.A.S. - Grab A Sprite - A quick glance at the program did not reveal any Final Cartridge specific code though. As well found at cascade64.de


Final_Cartridge_all_rr.c64.org_2010-05.rar contains:

Trivia

  • 64'er June 1986 has a comparison on the Power Cartridge from KCS and The Final Cartridge. The cartridge from H&P reviewed here has a few things different than one would expect from a normal FC1 - especially at that time. (tbd)
  • Clones were made of many cartridges but unfortunately photos of them are rare. (todo-> clone gallery)
  • FC3 manual: FREEZER, Tools, Schnell-Lader, Drucker-Interface Uwe Stahl (update this)
