Welcome\u00a0back to 8-bit days \ud83d\ude42<\/span><\/p>\n

The day Alcofribas kindly invited me to the 10th anniversary of <\/span>7DX Demo Party<\/a>, I knew that I had to do something special\u00a0for this event. Hosting Turkish demosceners for\u00a010 years via\u00a0enormous amount of hard work\u00a0and very limited resources,\u00a0certainly\u00a0deserves support!<\/span><\/p>\n

Since there has never been an official<\/em> Amstrad<\/a> release before\u00a0at demo parties in Turkey, I decided to go back to my roots -early 80s- where I used to do a lot of 8-bit assembly language coding.\u00a0I thought, writing a simple Amstrad intro in 256 bytes would be great. –\u00a0(Yep, size does matter!)<\/em><\/p>\n

<\/p>\n

I did the coding\u00a0in Z80 assembly language using WinAPE<\/a>, and tested it on an Amstrad CPC 6128 that I borrowed from Alcofribas. After a few days of PUSH<\/strong>ing and POP<\/strong>ing, I coded something that looked OK to me.\u00a0<\/span>When I e-mailed it to Alcofribas his response was good, but not great. That was an implication of “you can do it better!”<\/em> \ud83d\ude09 So, I decided to squeeze a few more bytes here and there, while adding more features…\u00a0<\/span>And finally, ended up with a much better version. This time, feedback from Alcofribas was more satisfactory; “Oh My God!”<\/em><\/p>\n

I have released the “256 byte Overscan MEGATEXT Intro<\/a>” at\u00a07DX Demo Party 2011. – (December 24, 2011)<\/p>\n

It is a greetings message scroller, featuring\u00a0silky smooth 50 Hz hardware scroller, overscan display, and\u00a0complete Amstrad palette (27 colours) on screen at once, all within 256 bytes.<\/p>\n

With regards to kind responses from international Amstrad scene, I have released the source code as well. You may find it here<\/a> at the CPC Wiki website.<\/p>\n","protected":false},"excerpt":{"rendered":"
