Dumping (And Playing) LeMans Ultimax Cartridge on the Commodore 64 (Part 1)

Рет қаралды 21,282

Күн бұрын

1982's LeMans racing game for the Commodore 64 is one of my all-time favourite cartridges, though it has a quirk that's always puzzled me. I'd like to disassemble the code for the game to figure out what's really going on, but my Super Snapshot machine language monitor isn't compatible with cartridge games. So I'd like to dump the cartridge ROM to a disk file, but that's especially tricky with these UltiMax mode cartridges. Join me as I finally figure out how to dump, load, and run this game from disk, in preparation for another video where I actually look at the game code in detail.

I swear I played this game on an "arcade cabinet" in the 80's in a beach town in Turkey. It was not Monaco GP. Later when I got my C64 and played this game I was excited to play a game that was identical to the arcade. Now I realize, that cabinet must have been a custom made with a wheel connected to the paddle. :) Glad to see another video that sheds light to an important part of the gaming history. 31:00 - very interesting, and makes total sense!

The Video inspired me to dump my own old supergames cartridge from childhood the old school way, but I am not finding it right now in my mess... never dumped a cart on the C64 yet. I ported stuff from cart to floppy using a PC and emulator, but never really dumped a cart myself. I feel the urge to do that now... Great video as always

The game reminds me a lot of a more advanced version of Car Race [], which was made for a PET users club in Japan by the late Satoru Iwata, who would later join HAL Laboratory, then would run it, then would end up running Nintendo during some of its most prosperous years. An absolute legend.

@8_Bit 5 ай бұрын

Yes, and seeing as the programmer of LeMans is unknown, there's even a chance Satoru Iwata himself worked on this game. We know he programmed the VIC-20 game Star Battle (known as Galaxian in Japan) when he was with HAL Laboratory.

Thank you for this video! I managed to dump a strange cartridge I found on eBay ages ago called "The Operating System", but at the time I didn't have the machine language knowledge in order to make sense of the code. Now I can finally go back and take a look at what the cartridge is supposed to do, since there's virtually no info about it on the web. Lemans is one of the first cartridges I got for my C64, although my paddles are the gray ones from Commodore with the fire button up on top. It definitely was an endurance test to keep that button held down with your thumb for a long long time in order to get the high score!

@11:28; line 7 is I/O line for DE00-DEFF. It's counterpart is line 10 for DF00-DFFF. In the programmers reference there is a section describing all the input/output assignments in the D000-DFFF area, where DE00 to DFFF is mentioned as "Reserved for Future I/O Expansion". Cartridges basically have access to this I/O area. Not sure if the carts you've shown there do anything smart with it. I know for a fact that the "KCS Power Cartridge" uses the I/O section to do some of its trickery and your beloved super snapshot uses it too.

How great to see you do a video on LeMans/Le Mans/Lemans/Lemons! This was the very first game I ever played on a C64, it was a pack-in cartridge when we got our machine new in the 80's, and was one of my all time favourites as a result. I was devastated when my little brother "accidentally" cut the cord on our paddles back in the day and I couldn't play it with them anymore - wish I'd had present-day-me skills to be able to repair them!

Neat! I ended up with a couple different versions on disk with joystick control, maybe one was from you? It was surprisingly playable by joystick too, and was actually superior when trying to get out of the pits as it didn't have that flaw of giving the player no indication of the paddle position it would track to when control was handed back to the player.

This turned out to be much more interesting than I thought it would be! I was expecting you to take the ROM IC out of the cartridge, read it in a programmer, then save the resulting binary file. I was certain that was going to happen when you put the cartridge in the vice --- presumably to crack it open 🙂. Dumping the ROM from a C64 is less destructive and more fun!

back in the old days, most of us had modified C64 with dual kernel like for example the SPEEDDOS modification very popular in Europe.

Ha, when I was little I didn't know this pronunciation of "Le Mans" that you're going with, so I pronounced it as "leh * MANS" (like the word "man's"), haha! But even this "leh * MAWNS" pronunciation is actually incorrect, because Le Mans is _French._ So it's really more like "LOOH (long) * mah(n)" -- no s, and the n has kind of a soft, nasal, barely-there sort of sound. But Commodore's having used all-capitals doesn't affect the pronunciation anyway, since that's not in a context in which all-caps would come up as a basic emphasis, either because _B/I//U_ were not available, or in a simple pronunciation key.

Amazing video once again. Quick question: how does the monitor load or print anything if the kernal rom is banked out?

@8_Bit 5 ай бұрын

The Super Snapshot is constantly banking things in and out to be as transparent as possible. I guess we'd have to invert terms for it, so there's the "apparent state" of the machine where I've banked the KERNAL ROM out, but in reality the SS will bank it back in when necessary. Whenever it fetches or stores a byte, it needs to do the appropriate switching first. It seems like a lot of work for each byte, but it's still plenty fast enough for doing things like disassembly or memory dumps.

The bug discussed at 35:30 doesn't affect the ML monitor in THE FINAL CARTRIDGE III. On the FC3, you can issue the command S"FILE",08,E000,0000 and get the full 8K as desired. That's a neat trick with the alligator clips! -- JC

You are definitely right about not many games using the paddle controllers for the Commodore 64. I wonder why? There definitely was no shortage of driving games for the system!

@8_Bit 5 ай бұрын

It might have just been a supply and demand thing; relatively few Commodore owners had paddles so developers would be reluctant to design games around a controller that a smaller percentage of customers owned. Atari included paddles with every VCS for the first number of years the system was sold so more games supported them. Then Atari stopped including them with the system to cut costs, and we see almost no new paddles games for the 2600 later in its life.

It would have been MORE clever if the Ultimax memory map wasn't different from the C64 memory map.

@8_Bit 5 ай бұрын

The Commodore 64 essentially switches into an Ultimax (aka Max Machine) emulation mode when those particular pins are grounded, reconfiguring its memory map to match. It was a fairly easy thing to implement (mostly done in the PLA, I think) and it meant that all those great Ultimax games being made in Japan could become C64 launch titles as well. In Japan they were sold as Max Machine cartridges, but exactly the same cartridge (with a different label) was sold in North America as a Commodore 64 cartridge.

@@8_Bit: I assume saving location $FFFF is unsupported and was never even contemplated back in the PET/VIC days where these routines come from. Really, the best way to handle this is to make a program that does a normal BASIC LOAD and RUN and copies the cartridge/character data from ~$0850 to wherever it needs to go, sets the memory configuration, and calls it.

the trilogic expect cartridge was better

@davidwalsh390 5 ай бұрын

I had that! Pitstop 2 was better but it took a billion years to load it.

Pitstop 2 is great but I actually prefer the racing gameplay of LeMans. I understand I hold a minority view on this matter :)

The s is silent though

When I was a kid I pronounced it LEE-muns.

@vancetuber7305 5 ай бұрын

The "S" is silent in the correct pronunciation of "Le Mans".

The BIN Format is a Eprom Dump usable to burn to a new eprom, this needs no load adress bytes.

Yes, that last section of the video was to show the difference between a .bin file and a .prg file, and how to load a .bin file from disk into the correct location in memory. There are many .bin files online and sometimes people want to load them from disk and then are confused why it doesn't work.

So let’s patch it for 24h and stream a game run in realtime :))😅

Btw for such an early game it’s great game mechanic and paddle well used / does it have a joystick or keyboard mode?

@8_Bit 5 ай бұрын

The official LeMans cartridge is paddle-only, but there are unofficial hacks spread around on disk and tape that modified the code to use joystick instead.
