No, unfortunately I haven't insomnia, that would help doing much more things However I'm reading the docs, and it's an interesting machine. Questions regarding the architecture of the system are coming to my mind, but for now I'm just reading

Thank you very much for the precious information. This is a good starting point. I'll read everything and I will update you soon. There will be probably things I will ask you Thanks again.

Hi to everybody, I have coded several Action Script emulators such as Sega SC-3000, Sega Master System, Coleco Vision, MSX1 and some arcade games ( Pengo, Crush Roller, Pac Man, Lady Bug, Solomon's key and Bomb Jack ). I always have wanted to learn more about the TI-99/4a, and maybe to code a special online emulator. Can you suggest me a good doc to read to learn how this computer works? I mean, something that let me go deep in the hardware, which talks about hardware specs, memory map, bios, functions, I/O, everything... Is there something that explains what happens when you turn on the machine with or without a cartridge, or how the memory mapped I/O ports are read or written ? What is the Ti99 Bible ? Thank you.

Thank you! I appreciate it... If I need help for any kind of AS3 coding I'll PM you! Concerning the emulator, there are news !!! It is becoming multi system I Have just done the MSX implementation, so now you can play also some MSX titles... http://www.digimorf.com/ASmsx I suggest King's Valley 2, really cute! on the box of konami games In addition to the SN76489, there are new Audio Chip classes AY-3-8910 and thE SCC for Konami games. I've also implemented the Konami4 rom mapper for 8k rom paging and a generic one for other games... Some Scanlines Video FX also to test speed. Hope you like it...

HI! I'm sorry for no updates in game list, but I had to fix the code to make standard some functionalities. Now on ColecoVision emulator is possible to save and load memory states... and there is the pause button like the SC-3000 emulator. Colecovision AS3 Emulator This project is growing, and the code is becaming little by little more "standard". This means that if i would like to implement some other machine, It should be possible with less work. Actually I could play some MSX titles too, but still a lot of work has to be done for this system. Anyway... for now enjoy saving loading feature As soon as my job will leave me some spare time I will update the game list. Bye!

Thanks a kit, could you do it also for the SC 3000 emulator? It works now! Thanks I tried the game The Castle on the SC 3000 page, it seems it does not work. Just fixed X and C keys for SC-3000 emulator, and added SEGA BASIC Level III B to game list! Don't forget that it is possible to save and load states in BASIC L III B too. This means tha you can share also binary memory files with other users ! SEGA BASIC Enjoy!

Thank you very much! I need to check if there's a way to boost Flash Player to run applications faster in older system... You are right, keyboards layouts may vary, so for now I've changed keys, and put X & C as you suggested, but in my "TODO" list I've put a keyboard configurator, with a possibility to save/load your own configuration. I've also fixed the "*" key, it was a mistake. there was the backspace code instead... now the DEL key should work Now it should work Yes, I've just saw that, maybe there is a timing problem still to fix Not so easy, unfortunately the last release of Flash player doesn't support joystick So it would be necessary some extra program to manage a local stream connection... so no joystick right now, sorry Thank you for your help and your appreciation very much! "E" and "F" games on site now!

If you save the page on your PC is not possible to play games since game roms are not available for saving. I'm planning to activate a memory state saving/loading ( like the SG-1000/SC-3000 emulator ) but only chip informations and ram will be saved. Maybe in future I will release a desktop version of this emulator.

Unfortunately I haven't a real Coleco to test games with... But I think that general timings have to be fixed. Flash player is a little strange because its performance are related to Browser and platform. Actually I've found that FP runs a little faster on Firefox... But the real challenge is to write down a routine that keeps the same frame rate on all browsers The speed should be good since the main "frame drawing time" is around 4-5 milliseconds ( for a PAL 20 ms are the limit ) so the call to the drawing routine should maintain a good timing, but this maybe has to be deeply tested. I've found several JAVA emulators, but Flash is still quite unexplored... there are some around, but no audio is present. I'm glad you are enjoying! Letter D games have just been added... some of them still don't run, I need to test them.

Thank you, I will try to add some more games in the next hours for your "late nite gaming plan" I was looking for some documents on the use of memory, I would like to build a more "Colecovision oriented" memory mapper. And maybe if there's something in particular to know about interrupt. Actually there are some games that don't work and I need to find what goes wrong. I will MP him, thanks!

I was planning to solve the problem of a controller different from a simple keyboard... Actually as3 lets you read a stream from a socket, so it may be possible to write a "server" program, that catch joystick movements from your PC and send it to the Flash application, but this will be implemented in future if this emulator will be popular Anyway YES, there are still a lot of games that actually run, to be added... I need time But I think that little by little I will complete the list soon Thank you for your feedback on Burgertime this is really appreciated!!!!

HI! I've made some upgrade to the ColecoVision Emulator. Now many more titles can be played, and I've created a niceer page to hos everything like the SC-3000 emulator page. The VDP has been fixed, but the Z80 timings still has to be fine tuned correctly. ColecoVision AS3 Emulator Feel free to report some bug! Hope you enjoy this!

Nice start on the ColecoVision emulation. Thanks +1 Thank you, Actually I'm fixing the code of z80 and vdp classes to make them standard, so that I can reuse them in future. Little by little the list of games is growing, and soon I will update the page.

Hi to everybody! I've foung this forum thanks to a friend and I think it's really interesting! Also because I am ATARI years old I've had several systems in my childhood, and one in particular has been important: SEGA SC-3000. I've built a site dedicated to it, of course, but now I've just published its FLASH AS3 Emulator: PLAY SC-3000 There are some bugs still to fix, but it is fully functional. At the same time I've tried to make the ColecoVision version in this wip page: FLASH AS3 ColecoVision There are my first emulators... Actually I'm rewriting Z80 and PSG class to obtain a standard version for future uses. I would like to know if somebody has some interestng link or docs for ColecoVision, that will help me in going ahead with this project! thank you very much! Francesco.
