Merry Christmas!

Hey Kiwi, now I see you've graduated as a professional developer, that's exactly the way I made the scrolling.

Thanks everyone for buying your loose cartridge of Pumpkin Master. Now a little early XMAS present Press 2 in title screen to play Astro Pumpkin or 3 to play Pumpkin Catapult. Enjoy it!

I was watching your pictures and I've almost exactly the same game but in another package. Got this thing for 10 bucks. Of course the moment of day that you don't know why your phone rotates the pictures...

Let us not spread misinformation and let me remember you TPR is one of the most informed persons in the world. Legally if you take a picture of a thing in the public domain, the picture is your property, not the "thing". You can sell the picture if you like, but who would buy a badly taken picture? but still is your property. And I went also to Paris, the Louvre museum and took a picture of the Mona Lisa, because I wanted to have my picture along a memory of my trip. BTW I was reading that in Korea apparently the people likes to tell lies, so the only way to prove you went in a trip, is to show the pictures!!! Back to matter, any ROM published by myself in Atariage (or any other place in Internet) is my own property, and subject to my copyright. Unless I explicitely stated it is in the Public Domain, and then even you have moral rights, for example, if you did a drawing for kids and it's being used to promote something you don't like. Anyone selling physical versions without authorization is an abusive person, and anyone buying them is a moron. Legally the affected person has the right to demand both sides, but it would be a loss of time and money for a few dollars, so this is the type of thing where parasites take advantage. Solution: one person at a time, myself I never would use the services of an abusive person and never would buy an unauthorized repro.

Cool! thanks for sharing! I remember seeing some of these ads in magazines at the time.

IntyBASIC includes a mechanism to disable the ECS ROM by default. It's enough to use SOUND 9,,$38 as the first statement of program, and IntyBASIC will generate code to disable ECS. I need of course make it more elegant, but it's a small and quick solution.

Zero of course!

You really shouldn't talk about your girlfriend like that

WIP 2 gameplay clip I've worked like crazy for 9 days to make this 36 seconds video just this night. https://www.youtube.com/watch?v=474Ny4omzhc

Use the addition operator, for example BG00 + $8000 or BG00 + $4000.

I'm talking about memory used. One byte is 8 bits, but Intellivision works with words (16 bits = two bytes) Every value inside a DATA statement uses one word = 16 bits. If you want to save space, you need to fit two bytes inside a word and use a table to translate the byte value to the card value for screen.

Four full screens use 2K of memory (1K of words), so your limit without paging and not counting game code would be 84 screens (84kbyte ROM file) I would suggest to compress screens as byte, so two bytes fit in a word, duplicating your maximum to 168 screens. (this is the method I've used in Sydney Hunter and the Sacred Tribe to fit 100 screens)

TextEdit has a hidden ability to go to a line number, simply hit Cmd+L

It's hard to decipher without looking at your room selection code and random generation.

LD HL,source LD DE,target LD B,16 loop: LD A,(HL) LD (DE),A INC HL DEC DE DJNZ loop This copies data in reversed form, notice that DE should point to the last byte of your buffer (because it will be decrementing)

It's HL = Source address, DE = Target address, BC = Total bytes to be copied. For it to work, DE must point to an area between $7000-$73ff (the RAM memory of Colecovision)

You defined TEMPADD to be an address inside the ROM space (0008 ) and also your example would work a lot better if using DE instead of DL.

Glad it worked That's really cool! You made my day when you said my example game is useful Thanks!

It's because you're comparing the cards read with PI value, but if you change the background color, you must compare against the new value. Just make sure to compare with both values.

It's easy. Once it checked the bit for the square then #line is multiplied by 2. This means the next bit is then available for checking. Multiplying by 2 is equivalent to shifting left by one bit. I hope this helps.
