I'm not sure I understand these statements Let's compute: First line: 1 (dlist), 40 (chars), 40 (graphics), 1 (ref) = 82. 114 - 82 = 32 free cycles. Other lines: 40 (graphics), 9 (ref) = 49. 114 - 49 = 65 free cycles per line * 7 = 455 free cycles. Where did you get that '120 cycles' number?

Because I recently did some hocus-pocus with cycle counting, here comes some heavy nitpicking: First, one PAL frame takes exactly 312 x 114 cycles, that's 35568. Character DMA = 40 x 24 Graphics DMA = 40 x 24 x 8 DLIST DMA = 32 (not 100% sure right now) PMG DMA = 5 x 240 (does _not_ matter if hi-res or not) Then you've noticed: Ref DMA = 1 on first line, 9 on other lines in mode 4. So, it's 312 * 9 - 24 * 8. Total DMA: 12488 cycles Free CPU: 23080 cycles So you were (just) cca 2000 cycles off. Also please note, that refresh doesn't always start on the same positions. It depends on graphics mode and HSCROL register (at least).

Desmond's Dungeon?

Why did the OSS produce Writer's Tool then? (I probably don't understand about what is that cartridge...)

To make the navigation easier I need some input - where did you get lost? It's HOME -> Atari -> Dumping Project -> 4th (or so) link from the bottom (called List of Atari Carts).

From a friend. Thank you again, friend! I was told that Mailing List is a cassette of CX4014 serial (hint, hint, nudge, nudge Other's are unknown until proved otherwise.

Hi, just my 2c: 1) The 'daughter board' is nothing special - just a replacement of 128k EPROM fitting into Atari ROM socket. Dumping should be as easy as dumping standard XEGS cartridge - see my pages how to do it (shameless plug ) 2) Re listing some proto RX numbers. See my pages for _almost_ complete list of Atari cartridges, including these (another shameless plug ) 3) Midi Maze got it name from the Midi<->Midi comm interface (MIDIMATE). I was said (and the menu shows it) that it allowed comm with the big brother (read ST version). It also allows playing on XM301, SX212 and a generic R: handler and also a solo mode.

Are your memory chips socketed? I would try to swap them for another set, just for a test. Maybe the PAL Antic has slightly different timing (especially the refresh timing) and is corrupting your memory. I still think that NIR-Pal is nothing like Real-PAL Wouldn't it be cheaper and more useful to buy real PAL Atari? I'm assuming you'll have to have multi-norm tv, what may be a problem in States.

Sometimes not. Hint: GTIA modes.

Take a hammer and perform a hardware mod of 1200XL's case. It's easy, for beginners To make pass thru, you would need the board with all connections and a connector. You won't buy it anywhere, but I think you can cannibalize it from dead 800XL.

Use the source, Luke!

What exactly does that mean? Silence? Distorted sounds? I remember it's the time spent in VBI playing the music?

2 games are not converted yet: RS Baseball (untranslatable because of controls) and Meteorites.

This is demagogic. You know that I was talking about the software, not the hardware, which you have already finished. I'm not going to discuss it more, 'cause: 1) You already have the product (I'm talking about hardware here) 2) Most customers would be from US, but since I'm on the other side of the pond, my sales would be worse, just because of international payments (I can't accept PayPal ) and international postage. I don't belive that Williams boards are refurbished. This is nonsense. If you want to spend some money with me, send me $300 and I will send you Lucasfilm 4-in-1 multicart rom image I think that would be seller...

My point is not that his prices are generally high. I accept the argument that if there's demand, let them pay for that. My whole point was, that I feel, that he's making money of other's work. I can accept whole deal in this form: pcb is new, costs X1, case is new, costs X2, work, eproms, labels etc. cost X3. Rest is his profit. I still think that the profit is cca $20 for each cart, which is way too high to be 'fair' when we both know he's selling other's work. It's similar as the Atari Software CDs. If somebody sells then for $5 + postage, nobody will object, I think. But if somebody sells them for $50... This is just question of proportions: what is fair 'profit' on other's work and what is not. My point is that I can't believe that in those $45 are just fair 'distribution' costs.

You've missed my point. Althought I think that $45 is bit too much for 30 games multicart, I don't think it's terrible price. But asking the same for the game which could be done in few minutes, that's certainly unfair. Also if we know that it's still the old good piracy.

The price: this is Lance's domain, I don't know anything about that The system: I've used Lance's Williams64 bankswitching cart How it was done: First I cut the disk image in pieces: One screen is 4096, there's 7 of them = 28672 Title pic with dl is 8272 Main code data is 37120 Our banners is 2240 Loaders and such stuff is 416 Total: 76720 Cart size: 65536 Then I compressed the large static chunks of data: Title pic was compressed to 2847 bytes (34%) Main code was compressed to 23635 bytes (64%) Created the exe (I use special cart exe loader) and put the whole stuff in correct cartridge layout. Main executable (unpacker, exe-loader, banner, title, game, cart driver) is then 29184 long exe file, screen data left unpacked, just to allow shorter 'cart driver' code. In the result, it leaves me with 7168 bytes free on the cart Reading of the additional screen data was done this way: I found sio reading code in main executable, then I replaced it by jsr to 'cart driver', which resides in unused memory (this was quite hard to find such space in Intl. Karate, as it uses whole 48k). It does bank the cart in, copies the data to ram and then turns the cart off again. You may try that with magic 'ADZM' cheat, you may compare the speeds of the disk version and the cart version Back to 'pricing' topic: Eprom needed for Alley Cat - 32k x 8, 150ns, PLCC32. End user price, quantity 1 - $3 Multicart: Mark says 1MB, my shop only carries 512k - 29F040, 90ns, PLCC32. Price $3.60 As you can see, there is almost no price difference, cart shell, pcb and manufacturing work still costs the same - no matter how much data are put on the cart (just the burning process is shorter). Re: Mule - it's not real multiloader. It's just first part, then second part and never touching the disk again, so it could be done in a similar way, but without any fancy 'cart driver'.

First, it is NOT 30 times more expensive!! In fact it is LESS than the Multi-Cart. Okay, so it's 20 something more expensive. Does that make a difference? Yup, I have idea. If Mr.N uses the code I gave him, it takes about 5 minutes to do single stage exe (maximally). I thought you're using 29f040 maximally. Okay, in such case also 30 games in a multicart is too low number. If I take about 20 kbs per game uncompressed, you can stuff there about 50 games. Don't shout that loud. I can hear you.

Stupid question: why is this game 30x more expensive than the multicart one? Are you paying royalties to Mr.Williams? If the max is 512k and rest of the expenses are constant this seems rather unfair (read rip-off) to the people, as you can always release it on the multicart (for example with other Synapse/Synsoft games). Offtopic (concerning the multicarts): Not mentioning the need of the 400/800 machine for some games when you can drag the translator on the cartridge. Just my 2c.

Hi, how were JagCDs packaged? In digipaks and then boxed? Or in jewelboxes?

Hi, anybody has hi-res overlay scans? (300dpi, low compression). I would like to make some printing/lamination hocus-pocus. I need Baldies and Blue Lightning. thanks,

Hi, is anybody using BJL with uploader running on 'real' Windows, ie. NT based? (NT4, W2k, XP) Is any special hocus-pocus with parallel port, some device drivers or something else needed?

What schematics? Everything is IMO hidden inside the Maria. And if I'm not mistaken, no mentions in MESS code either, except for: if(data & 0x01) { maria_flag=1; } if(!a7800_ctrl_lock) { a7800_ctrl_lock = data & 0x01; a7800_ctrl_reg = data; //this does os/cart bankswiting if(data & 0x04) memcpy( ROM + 0xC000, a7800_cart_bkup, 0x4000 ); else memcpy( ROM + 0xC000, a7800_bios_bkup, 0x4000 ); }

Lords of Karma?

Hi, it would be still nice to know how does it work. JEDec anyone?
