* исходники теперь компилируются под MSVC6 (было MSVC7). Sources are now compiled by MSVC6 (was MSVC7)
- в связи с этим выброшены фильтры AdvMAME, FrameResampler. Because of that the filters AdvMAME and FrameResampler are removed

! CD-ROM не работал под Windows 9x, теперь работает. Сделан обход глюка, который возникает вот здесь, по непонятной мне причине: CD-ROM did not work in Windows 9x, it works now. Walkaround of bug, that appears here, was made:

int ATAPI_PASSER::SEND_ASPI_CMD(void *buf, int buf_sz)

! буфер на 256 значений YM2203 убран - мешает цифровому звуку через YM2203. Buffer for 256 YM2203 samples is removed - it hampered the digital sound via YM2203
+ ввод из клипборда теперь поддерживает и русские символы (кроме двух:
заглавная Ё понимается как Е, заглавный Ъ - как апостроф). Paste from clipboard understands Cyrillic letters

* дополнен комплект файлов. File set is filled up

        version 0.36.2                  28 mar 2007 (Alone Coder)

! клавиши в max speed режиме опрашиваются каждый фрейм:
temp.inputblock = 0;//temp.vidblock;
а то не всегда реагировало на NumLock в max speed режиме.
Keys in max speed mode are scanned every frame, for better responsibility
of NumLock in max speed mode.
! звуковой буфер не чистился (sound_stop()) в меню Save disk
(main_save(), correct_exit()).
Sound buffer was not cleared in Save disk menu
! вываливался при показе меток длиной 10 (sb Elfh).
Emulator crashed when tried to display 10 char long labels
* 0 не показывается как метка.
0 is no more shown as a label
! что-то исправлено в интерфейсе с BASS.DLL (fb molodcov_alex):
if (!BASS_ChannelPlay(hmod, FALSE)) reportError("BASS_ChannelPlay() [music]");
Something fixed in BASS.DLL interface
! порт #7ffd на Скорпионе дешифровался неправильно (теперь с учётом A12, как
#1ffd) - не работала листалка ACNews.
Port #7ffd in Scorpion mode was deciphered without A12 -
ACNews lister failed to work

        version 0.36.3                  28 apr 2007 (Alone Coder)

! исправлена палитра. Palette is fixed
! Z80: в операциях записи в память сама запись (wm()) делается после увеличения
счётчика тактов (cpu->t+=) (если два байта, то 2 раза cpu->t+=). Важно для мультиколоров.
Z80: memory write procedure (wm()) in memory write operations is called after increasing
the tick counter (cpu->t+=) (in two-byte operations cpu->t+= is made twice).
Important for multicolors
! исправлена русская буква "м" в anti-text64 - показывалась как "m".
Anti-text64: fixed Russian letter "м"
! TurboSound FM: FM часть заглушена в 4 раза в соответствии с реальным устройством.
TurboSound FM: FM is 4 times more quiet as in real device
! поставлен шумопонижающий фильтр (нужно для beeper'а). Кто знает как -
помогите убрать щелчки на границах 20ms кадров! Если просто заполнять первые
2-4 отсчёта кадра предыдущим значением, то щелчки на бипере исчезают,
но появляются щелчки на AY... Noise reduction filter
added (for beeper music). Please help to remove that clicks in boundaries of 20ms frames!
If I simply fill the first 2 to 4 samples of a frame with preceding value, then
the beeper clicks are disappearing, but AY clicks appear...
! звуковой буфер не чистился в меню Save sound. Sound buffer was not cleared
in Save sound menu
