ISO Loader 0.8.x Beta + preview of DreamShell v4.0 RC 5

[CrisMod]

@SWAT - @megavolt85, i discovered another problem here with the enviroment settings.

When i'm going to install the new enviroment with latest upgrades to build the `Dreamshell RC5 / ISO Loader 0.8.x`, I have been doing this already for 2 times with fresh Enviroment.

The following steps here:

`
sudo mkdir -p /usr/local/dc/kos
sudo chown -R $(id -u):$(id -g) /usr/local/dc
cd /usr/local/dc/kos
git clone https://github.com/KallistiOS/kos-ports.git
git clone https://github.com/KallistiOS/KallistiOS.git kos && cd kos
git clone https://github.com/DC-SWAT/DreamShell.git ds
git checkout `cat ds/sdk/doc/KallistiOS.txt`
cp ds/sdk/toolchain/environ.sh environ.sh
`
It download the latest master branches source files, and when i check the file that i need to change - as @megavolt85 told me - in "usr\local\dc\kos\kos\kernel\arch\dreamcast\hardware\network\broadband_adapter.c" there are the latest changes:

From:
`
/* Shutdown */
int bba_shutdown(void) {
/* Shutdown hardware */
bba_if.if_stop(&bba_if);
bba_if.if_shutdown(&bba_if);

#ifdef TX_SEMA
sem_destroy(&tx_sema);
#endif

return 0;
}
`
To:
`
/* Shutdown */
int bba_shutdown(void) {
/* Shutdown hardware */
if(bba_if.flags & NETIF_RUNNING)
bba_if.if_stop(&bba_if);
if(bba_if.flags & NETIF_INITIALIZED)
bba_if.if_shutdown(&bba_if);

#ifdef TX_SEMA
sem_destroy(&tx_sema);
#endif

return 0;
}

But when I start the next step under Toolchain section arrived on last command line `make && cd ../../` it will reverse all the KallistiOS.git source files in some old version, in fact example on `broadband_adapter.c` will go back to another old version where the part on 1311 lines will reverse in below old settings:
`
`
/* Shutdown */
int bba_shutdown(void) {
/* Shutdown hardware */
bba_if.if_stop(&bba_if);
bba_if.if_shutdown(&bba_if);

#ifdef TX_SEMA
sem_destroy(&tx_sema);
#endif

return 0;
}
`.

And this will create me a problem when I'm going to build the new DS_CORE.

Can you please write for me the steps how can I re-reverse in new KallistiOS settings and I upgrade the Enviroment, at least I will be able to make fully working DS_CORE to continue with test.

Thank you in advance.
