DreamShell v4.0.4 Release

[Elgor4uk]

Holy BIOS заработал, нужно было через VGA загружаться. А вот Devkit_NoGDrom не работает ни VA0 ни VA1, хотя GDrom диск крутит с черным экраном и без звука.

Перепрошил Holy BIOS новой сборкой. Результат - чёрный экран, но звук загрузки Dreamshell есть.

Только VGA поддерживается.
VC игры не работают на этом биосе, может еще какие-то.

I flashed the regular bootloader-retail BIOS. Is it possible this is causing my issues?

I did test NBA 2K2 and NFL 2K2 with default settings and 8с004000 and now they boot fine. I guess the correct settings changed from the last release. I still can't boot Ooga Booga or Floigan Bros. though. I tried with two different CF cards (Transcend and SanDisk) but they don't work on either. Tested both low-level and 8с004800 without low-level. I also tried the ide.bin from both 4.0.2 and 4.0.3 and they still don't boot. Reverting DreamShell back to 4.0.3, they boot fine.

No, bootloader-retail has better compatibility than HollySH.
It's very interesting how the core affects the launch of games for you...

Я прям все-все вариации не пробовал, их довольно много сейчас. Плюс я переделал механизм их сборки, теперь фичи патчатся в 2 версии биоса (retail/devkit), а не для каждой фичи хранится в репозитории отдельный файл.

Я протестировал Devkit_NoGDrom + Devkit_NoGDrom_Wildscreen + Retail_NoGDrom_Wildscreen = они с чёрным экраном.

Хмм nogdrom патч плохой что-ли, попробуй другие если есть возможность.

Edit: да nogdrom биосы не работают, разбираюсь...

I rolled back some more similar changes as before in KallistiOS to get even more stable and made a couple of fixes to DreamShell itself.
Fixed nogdrom BIOS firmware for Dreamcast and booting from old bootloader. Re-download release to get it.
I hope this is the last fixes for this release. Thanks all for testing and reports!

Если прошить BIOS с пометкой Wildscreen, он будет поддерживать только широкоформатные экраны и пропатченные игры? Или 4х3 тоже поддерживаются?

[SWAT]

Another issue found in KallistiOS, CD-ROM streams are broken, I've disabled it since for DreamShell it's not matter in general.
Re-download release if you want using CD.

Это только для стартовой анимации, на игры это никак не влияет. Для них нужны патчи и они не универсальные к сожалению.

1. Здравствуй, SWAT. Добавь пожалуйста пресеты в ром диск из этого сообщения

2. У загрузчика 0.8.4 как у 0.8.3 сохранилась проблема с запуском некоторых Homebrew игр, например Battletoads.

1. OK.
2. Где скачать? Интересно даже, как это homebrew и не запускается.

- Full FlashRom emulation on NAOMI, including writing to the used dump file. Now you can setup internet connection for Dreamcast online games.

Работу этих образов я исправил и пресеты обновил.

Try latest update. Now I can boot even Ooga Booga and NHL2k2 without low-level. Also added presets for PSOv2, Planetweb 3, XDP, etc..
This is the best iso loader for me right now.

Everything works for me now except for Ooga Booga. But I found something very interesting. If I use the ide.bin from 4.0.4 from within DS 4.0.3, it boots fine. So apparently the issue is with the core and not with the loader.

Edit: Also, any idea why I get this debug info when I boot Pro Yakyu Team de Asobou NET? This happens on 4.0.3 as well but only the numbers on the top-right. The info on the left isn't there in 4.0.3.

This is a very strange dependency. In this case, it probably makes sense to launch from IP.BIN, but with this game, that's probably impossible on a 16 MB Dreamcast. It runs fine for me on a Japanese Dreamcast...

I guess the game just look in low memory something (debug tool?).
Try high memory for the loader or just shift a bit in low.

Yeah it's very strange that it works for you but not me. I'm using a US DC but I wouldn't think the region of the DC would make a difference.

I tried a few different ones, both high and low, but the debug info still shows up.
