nanochess

I'm between three points, I'm a developer, I'm a buyer of cartridges and sometimes I'm a seller. As a developer, I'd would trigger my very human vanity to see one of my games reaching a very high price, even if I don't get any of that money (though it would be nice to get some ). As a buyer, I'm very sad to see that some Colecovision cartridges reach a price so high that it's irrational and I possibly never I will manage to get complete my collection. I've been caught in sites with offers at a nice price but dirty label cartridges, but I'm learning as I'm new to this (by the way mumbai surprised me with reasonable prices and high quality) As a seller here at Mexico, mostly of Atari carts through my friends, I simply divide my final invoice (including shipping) by all cartridges and I add a reasonable 30% so I can do discounts, and always I'm ending with better prices that all the cartridges available at mercadolibre.com.mx (our local ebay). So I think I'm not greedy and again I hope to buy some more cartridges and repeat the cycle. So as we live in a free market, I believe Rellik111 has the right to sell the games at the price he wants. But the other side of the free market is that sometimes there is no moral so a lot of people will feel that is harsh, specially if as said he asked to get a special item without telling about his intentions (in this point would be fair to share the money with the original seller, IMHO) Anyway doesn't look like Rellik111 has a queue of people waiting, people will start learning there are better offers and economy will get equilibrium so Rellik111 will have to reduce his prices, so there is limited damage (like I've learned to ignore ebay ;D). Anyway remember the old joke of the man selling replica statues, he had two lots, one at 5$ each and other at 10$ each, someone asked what's the difference, "none", he said, "but some people prefers to buy the 10$ statue" . If we can understand this then I hope we can come in peace.

Then already there are two mad guys: he and me, because I've also translated my games from MSX to Colecovision, and I would port to SG-1000 too but I don't know who could manufacture the cartridges . And crazyboss has suggested me ports to Memotech MTX-512 and I've heard that the Tatung Einstein is similar

The completed boxes look even better I'm still astonished by the quality of artwork you provide for your boxes and carts.

When I got an Atari for the first time I though I would need the balun, but there's a trick. If your TV antenna has two bolts then it has 300 ohms input, but if your TV has a connector looking like RCA but bigger then it has 75 ohms input (almost all modern TV are this way) and you can connect your Atari directly to TV without the balun.

I've played it recently and it's a great remake! thanks for sharing, Internet is so huge that we can easily miss many things.

Most open source programs are free for non-commercial usage. Your problem would be that many of the required ROM for emulators are still under copyright but I don't think there is any problem if you don't earn anything, anyway the machines are plain dead, by example BlueMSX includes lots of ROM from MSX machines and Colecovision. (note I'm not saying that this is legal) On the other side, don't include games ROM, most companies aren't very fond of this.

A pretty difficult topic. If I were a collector I would be very worried to lose of sight a valuable prototype, and by valuable sometimes we're not talking of money but some emotional value. Next point, some collectors (as I've read before in Atariage) doesn't want to release even ROM files because they think his prototype loses value or they paid a very high price so they don't want everybody else to enjoy it for free. Another point, other collectors (also seen in Atariage) would like to release ROM files but they don't want to see it commercially distributed, and though here in Atariage people is very educated, we have seen the ebay surge of not-so-good people that marks everything as "rare" Anyway my proposal is that collectors should take good quality pictures for the history's benefit and get equipment to dump ROM on their own, as the ROM continously oxydizes and would be a shame (even for the collector) to lose something unique. Maybe sometimes even the collector wants to remain anonymous, so I suggest to send pictures to NYAD just to tell that in effect the prototype exists, and maybe in some time, the collector would like to share the ROM under his terms, maybe even selling the dump and keeping the original prototype, I'm sure everybody here would contribute some money in order to release ROM for community benefit. Certainly I would put some money to contribute to pay for the ROM of Wizard of Wor or He Man.

It is the problem of any thread using the "vs" (versus) word in title (check C64 versus Atari) People starts thinking that one of the two should win. But reality is that though I understand both Z80 and 6502, I prefer more Z80. And everyone here have their own preference. That's all folks! Now go in peace and write some good code.

The Colecovision version includes new graphics, enemies and music, plus new challenges, besides it plays in Colecovision

Thanks for sharing!

Very well rounded game Congratulations!

I got it right like those famous singers that always shout "Thanks Mexico" Don't worry, as far as I know there is no way to correct titles

What's the Colecovovision?

Just for the records, everything from MSX up to MSX2+ used only a single Z80 CPU. I'm wondering were Hitachi HD64180 was used. When MSX came up to the United States, the Colecovision already had the market, same graphics capabilities and MSX had the price too high, so it couldn't have been successful.

The Z80 machine code is higher level than 6502. Unless you have some macro capability in your 6502 assembler you're going to spend a lot of time repeating some small routines for 16-bit operations. In Z80 there are a lot more registers, instructions to move a block, search for a byte, output block to port, input port to block, adding/substraction 16 bits, adding/substraction without carry (in 6502 you've to clean Carry flag,) conditional returns/jumps/calls (saves a lot of code.) As said before the 6502 needed more help from peripherals, so there is the C64 where the VDP has pixel scrolling capability and the PSG could do FM style sound, everything without processor help, even the Atari had a lot of help with its associated chips. While the poor Z80 stuck with not so powerful graphics and sound, like the SG-1000, Colecovision and MSX, and the better were the Sega Master System, and MSX2 and MSX2+ (this one with FM sound) that came a little too late.

Indeed a great trouble. Many years ago I bought an offer of a hundred of used EPROMS and for some reason, half of them never could be erased properly, other quarter never could be programmed properly, so I ended with twenty or so functional EPROMS . It would have better to buy new EPROMS

Except when old appearance is required, like your Side Trak game that reused old Coleco cases to look like a classical release

You would be surprised, EPROM and PROM are still in great use all around the world for small appliances and industrial machines. These chips are more trustable than Flash chips for many applications.

In order to make a nice video there would be a need for a good script and somebody with a good voice. It could be interesting to do a documentary about development of Princess Quest or Zombie Near. I have backups per day of development so it could be showed how them were improving. I'll think about it.

In fact there are two books about Toledo Nanochess (my own chess program!!!,) one by Lambert Surhone and other by Jesse Russell. Both say "quality content provided by Wikipedia". What makes me to wonder because the Wikipedia entry for Toledo Nanochess barely fills a page for a book. These things should be prohibited because trigger people to think there is indeed a book about my chess program. Besides these pirates are earning dollars for each book (somewhere I've read one of these "editors" have 300,000 different books published based on Wikipedia articles) http://en.wikipedia.org/wiki/VDM_Publishing

I suspect you're right as Coleco was based in USA. Here at Mexico the metric system is the standard.

Pretty nice game! Congrats

My Zaxxon box measures 19x14x2.3 cm I hope this helps you.
