--- 2014-08-04

FIXED: # Can't interrupt fading of title screen.

	The problem is that fade_in_2 does a zero-length wait, and expects keypresses to happen then.

	fade_{in/out}_frame does a "simple wait", that is, keypresses are not processed then.

	So I changed that to a "regular" wait.

FIXED: # (Micro Palace, level 12) If kid is on the very left (in bottom row), then shadow is in wrong direction (looking left), and is constantly turning around.

	move_2_backward() is called from level12_shadow_anim()

	Local variable xdiff might be used uninitialized!

	Workaround: initialize xdiff with a big number.

	This behavior matches the DOS version but not the Apple II source. (AUTO.S, part around "wait until kid gets close")

--- 2014-08-06

	To be extra sure, I also added some compile time asserts about the sizes of all types that are used in the DAT files.

FIXED: If color 0 of a palette was not black, then it was not transparent.

FIXED: Under Linux, the game hanged randomly, because the main timer sometimes didn't generate its event.

	timer_callback() and sound_callback(): (in seg009.c)

		Remove and NULL the timer handle before generating the event.

	This also prevents the "SDL_RemoveTimer:" errors.

FIXED: # Digi sounds hang the game for 1 second (or permanently).

	Instead of opening and closing the audio device for each sound, keep it open (with a constant rate -> resampling is needed).

FIXED: # On windows, digi sounds are played with the wrong timing. You can hear this best when the kid is continuously running, or when a gate is opening/closing.

	Sound buffer length is 5512 instead of the 512 I set.

	With 22050 Hz samplerate, this means 0.25 seconds instead of 0.023 s.

	On Linux, the length is 256, and the timing is good.

	Fixed by replacing SDL.dll (1.14) with the newest version (1.2.15).

--- 2014-09-23

FIXED: The game quits in the intro, when Jaffar opens the door.

	play_digi_sound(): (in seg009.c) SDL_BuildAudioCVT() might also return 0 on success, but this is not documented in the docs of SDL 1.2.

--- 2014-09-25

FIXED: Index overflow in get_tile_div_mod() is kid is far off left.

	FIXED: # When doing the level 5 trick (backing through the gate), the kid appears in the room to the *right* instead of left.

	FIXED: # Level 5: If you back out from the room where the guard is originally (but the screen is not switched), the kid might fall through the floor at the level door.

--- 2014-10-06

FIXED: check_shadow(): (in seg002.c)

-	if (leveldoor_open == 0x4D) {

+	if (leveldoor_open != 0x4D) {

--- 2014-10-11

FIXED: Made the game compatible with Mac OS X, based on the suggestions by StaticReturn (from the Princed forum).

	(See also MAC_CHANGES.txt)

	- Renamed wait() to pop_wait().

	- do_trigger_list:

-	while (doorlink1_ad[index] != -1) { // these can't be equal!

+	while (1) {

	- Added typecasts to pointers (at malloc() calls for example).

FIXED: Fixed most things that caused compiler warnings.

	- Changed some pointers from void* to a better type.

	- Removed some unused variables.

	- Removed some unused parameters.

	- Changed the numbers in tile and frame tables from unsigned to signed where this was needed.

	- Added const to some parameters.

CHANGE: Now cheats are disabled by default unless the game is compiled in debug mode.

CHANGE: Disambiguated tilepos and tiletype.

--- 2014-10-27

CHANGE: Added a font inside the exe. (hc_font_data[])

CHANGE: Changed project type to GUI. This means that the (empty) console window won't appear under Windows.

CHANGE: Changed project's name to "SDLPoP" (was "port").

CHANGE: Changed the title to "Prince of Persia (SDLPoP) v1.11" (it used to say "... (SDL) v#.##")

--- 2014-12-03

FIXED: When doing Trick 95, the kid might bounce back from the wall a bit.

start_fall(): (seg006.c)

	seqtbl_offset_char(104); // start fall (when?)

+	play_seq();

--- 2014-12-20

FIXED: Don't quit if there is no sound device available.

	Instead, just disable digi sound.

	This can happen, for example, on a Raspberry PI emulator (QEMU).

init_digi():

-	quit(1);

+	digi_unavailable = 1;

+	return;

play_digi_sound():

+	if (digi_unavailable) return;

--- 2015-02-16

FIXED: Ctrl-S did not turn off mixer sounds.

play_chunk_sound():

+	//if (!is_sound_on) return;

	Note: this is not good for sound-based timing!

FIXED: Ctrl-S did not stop currently playing sounds.

turn_sound_on_off():

+	//if (!is_sound_on) stop_sounds();

	Note: this is not good for sound-based timing!

+	init_digi();

+	if (digi_unavailable) return;

+	Mix_Volume(-1, is_sound_on ? MIX_MAX_VOLUME : 0);

Note: If digi is unavailable, then load_sound will load the speaker sounds, so sound-based timing will still work.

FIXED: # If the game is in full screen, and I switch away (alt-tab) and back, most of the screen will be black, until it is redrawn.

idle():

+	if ((event.active.state & SDL_APPACTIVE) && event.active.gain == 1) {

+		SDL_UpdateRect(onscreen_surface_,0,0,0,0);

+	}

Note: In this case, DOSBox switches to windowed mode.

# GNU/Linux: Full screen resolution is 640*480 instead of 320*200.

	Also on Windows, depending on video card.

# GNU/Linux: After quitting (from full screen), the resolution is not restored, and an error message appears on the console. (X-error.txt)

	It seems that this bug disappeared, even from the old versions. It was probably caused by something outside the game.

# "Shift" of Shift-L interrupts cutscene too soon.

# Keys other than Shift won't interrupt fading of cutscene.

Not fixed yet:

==============

# game speed is a bit off (delay is longer than it should be) -- you can see this best with chompers

# Sometimes when jumping right to room 0: bounces back

	# also present in original

# shadow is invisible on level 12 if kid enters from left, or starts in the left half ... until kid pokes shadow

	Wrong ypos, you can see that when kid unites with shadow.

	# "enters from left": could not reproduce

	# "starts in the left half": also present in original

Leaks:

======

# LEAK: Going to new level allocates memory (~ 500 kB) that is never freed.

	free_chtab(): free_far -> SDL_FreeSurface

# LEAK: Switching between playing and intro allocates memory that is never freed. (play->intro: ~ 500 kB, intro->play: ~ 1 MB)

	clear_screen_and_sounds(): not freeing

# LEAK: still leaking

	intro->play: ~ 1 MB

	play->intro: ~ 340 kB,

offscreen_info = 192 kB, it is never freed!

Fixed

# LEAK: still leaking

	intro->play: ~ 772 kB

	play->intro: ~ 196 kB

	Level 1->2->...->14->1 : ~ 80 kB

--- 2015-02-13

FIXED: release_title_images is never called!

in start_game() added:

+	release_title_images();

+	free_optsnd_chtab();

Title: 44844 K

Level 1: 28184 K

Title: 45440 K

Level 1: 28188 K

Title: 45448 K

Level 1: 28204 K

45440-44844 = 596

45448-45440 = 8

28188-28184 = 4

28204-28188 = 16

Level 1->2->...->14->1 : 28188 -> 28296 -> 28304 ~ 108 or 8

Formerly not implemented:

=========================

DONE: # Coloring monochrome images (bubbles, chomper blood, story texts, gate top mask) and black blitter

	FIXED: # Top of gate looks weird (mask is drawn)

DONE: # Cutscenes

DONE: # upside-down

	FIXED # hangs / bad clip if kid drinks upside-down potion

DONE: # blitter 9

	FIXED # guard HP does not disappear if guard dies
