Really enjoyed it. Thanks edfed

it looks i'm to download these sources soon and study dos as it works, thank you

http://www.ibiblio.org/pub/micro/pc-stuff/freedos/files/distributions/1.0/fdfullws.iso
The same as fdfullcd, plus source code for all packages. This is a very large file. We mean it. No really, this is huge, and probably unnecessary except for the hard-core developer. If you want the source code for the "1.0" distribution, you're probably better off looking through the pkgs directory on ibiblio. You should not download fdfullws unless you are a developer who would like to view the source code.

edemko, FreeDOS 1.0 was a few years ago. I'll admit that updates are fairly slow coming, but they do come in pieces. You might be better off without using their installer (which is fairly broken, esp. networking). Honestly, it's nice to have a complete .ISO, but if you only want to study pieces, grab those individually. (The kernel src is like < 500k ZIP'd, found here; try 2038 as later has some regressions.)

Imagine the horror of booting DOS



Heh ??? What mouse what window ??? I tested in DOS, and the thing doesn't support the mouse About drug dealing, you know my opinion



COOL, silent update with source code (did not RTFS deeply nor tried to compile yet)

New bugs (newly discovered):

- Trashes the mouse and the clock
- Can't screenshoot with SNARF, and no built-in screenshot feature



Good, FreeDOS 1.0 is obsolete and buggy, get kernel 2038 (2039 has some nice improvements but at least 1 new critical BUG). FreeCOM regrettably hasn't been touched for years.

FreeDOS kernel in mostly C with some NASM.

FreeCOM is C.

Some utils are NASM (DELTREE, LBAcache, DEVLOAD, ...).

CTRAT is TASM/MASM/JAWASM.

A DOS kernel in ASM is DR-DOS / EDR-DOS (very historical MASM 3 syntax ) or RxDOS (MASM 6 (buggy) or NASM (unreleased) version).

it is intended to work at least under win98 and dos. for boot, it is OK, but needs a mouse driver if you want to drag the tetris window. and click on nexyt piece and other buttons.

at least, i will soon trow a new update, with HQ sound (using PIT channel 2)

???



it doesn't work and "trashes" the mouse - FreeDOS EDIT 0.7 doesn't work anymore after your TETRIS



COOL Please add screenshot support (2 BUF's per 64 KiB, PrintScreen copies into buffer, save on exit if something of someone got shot before ).

normally, it just uses int33h, 3 to read coordinates.
then, i don't see why it will trashes the mouse....

for screen shot, i don't know at all how to make the support for a real mode application ,and for win dosbowx, the OS is responsible of it...

but it is a good exercice (for me) in order to build a generic game and os framework..

for screenshot, i can plan on the creation of a bitmap file on prtscr, incrementing the file number for a new shot...
but even that(screen shot) is a single project that will take a long time to do..

Hmmm, it works fine in DOSBox or XP's NTVDM, but on my older DOS 586 PC only if EMM386 is loaded (and needs a reboot afterwards, doesn't clean up properly, i.e. restore timer). This P4 PC here doesn't seem to want to let it work at all in FreeDOS under any circumstance (crash, MCB error), so I dunno.

DOS386, obviously I meant drag the "fake" internal window, not "Window"(tm). For the hundredth time, I get no extra joy out of emulated DOS, but sometimes it's all that works! :-/

EDIT: Oh, and it's right ctrl that pauses, not left. (Why?)

I can't find any buttons, but they are irrelevant anyway, the arrow is completely frozen, moving the mouse by several light years results in the arrow moved by exactly 0.0000 picoinches on the screen ....



I do, see below



... Brew a 320x200x8bpp BMP file with M$-PAINT or whatever (see attach), copy the header, put in the palette (1 KiB at position $0036) and the bitmap (64'000 Byte's at position $0436 from bottom to top). Save at game exit (rather than immediately after pushing hot key).





OK, I did RTFS:

{1}



What is this supposed to do ??? There is no point to clear VGA RAM at $000A'0000 BEFORE INT $10, but what's worse, you apparently have 2 buffers at hardcoded addresses $0009'0000 and $0002'0000 - given that it's a miracle that I could play this Tetris at all You have to hog your buffers from DOS http://www.ctyme.com/intr/rb-2934.htm before writing any memory.

{2}

You apparently rise the PIT frequency to 1 KHz but fail to restore it before exit. Also, you should restore the PIT before any call to DOS, as the disk driver (BIOS or TSR) may rely on 18.2 Hz PIT.

{3}

You use the RDTSC instruction (really needed ???) so your Tetris will not work an anything below Pentium.

{4}

Heavy usage of 32-bit instructions in 16-bit code causes bloat and slowdown (also will not work on 8086).

{5}

Many calculations with constants.

{6}

Variables inside code - causes bloat, bad for PM programming

{7}

No comments (except title) at all - I do know who inspired you to this

{8}

Faulty filenames: "fixeddecimal.inc" and some more

{9}

Source does compile but doesn't match the binary released separately

{10}

Many strange files:

- 2 "PIF-PAF" files (needed ???)
- "FAS" file
- empty files
- "Comsys.com" ??? (hangs)
- "tetris.com" (that's exactly what compilation brews, but doesn't match the binary released separately, it works, but is "different" ...)

{11}



So you wrote it in just 1 day ??? After all, the God also brewed big things in just 1 day

{12}

MACRO's are included in a very "hidden" way

Unsurprisingly, see above

Right, but not only.

I do, see above.

Doesn't work, see above (I deprecate drug&drop as well as "windows", even if "internal" ...)

No extra joy, just extra posts to advertise

See above (+BTT-RR) why: so-called "DOS stuff" is NOT tested in DOS and fakes (like DOG-BOX, DOG-EMU, NTVDM, ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ...) forgive many CRITICAL BUG's (memory corruption (see above), invalid port usage (see other thread), usage of inexistent SoundBlaster, NTLFN, CMOVNTQ (indirectly), garbage I/O ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ..., ...) so they indeed make "DOS stuff" crappy (it works for everybody except those who have DOS)

edfed has some competition:

COOL, but is it FASM ???

One more: http://board.flatassembler.net/topic.php?t=11892

no, i'm not dead, just paused, because summer is not finished.
and no tetris update because i meet a problem with XP compatible version, it compiles, but it don't run at all...

DOS .COM, apparently TASM, but it wouldn't be hard to translate to FASM. Plays okay, but it just seems to restart upon game over without warning (which almost made me think I'd advanced a level, but there are none!).
